The measure of angle U is 74 degrees.
What is an angle?In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.
here, we have,
to determine the measure of angle U:
From the question, we have the following parameters that can be used in our computation:
△PQR ≅ △STU
If m ∠P = 62 degrees and m ∠Q = 45 degrees
The above parameters mean that
P = S Q = T and R = U
So, we have
U = R = 180 - P - Q -- by the angles in a triangle theorem
So, we have
U = 180 - 61 - 45
= 74
Evaluate
U = 74
Hence, the value of m ∠U is 74 degrees

Point A has coordinates (6,4) and point B has coordinates (2,7) write AB as column vector. Plz plz plz
Answer:
[tex]\overrightarrow{AB }=\begin{bmatrix}-4\\3 \end{bmatrix}[/tex]
Step-by-step explanation:
Column Vector
Vectors are matrices having only one column or one row. A vector having only one column is called a column vector, and a vector having only one row is called a row vector.
It's required to find the vector AB as a column vector, and we are given the coordinates of A=(6,4) and B=(2,7).
The vector directed from A to B is found by subtracting its corresponding coordinates:
[tex]\overrightarrow{AB }=<2-6,7-4>[/tex]
[tex]\overrightarrow{AB }=<-4,3>[/tex]
Now we express the vector as a one-column matrix as follows:
[tex]\overrightarrow{AB }=\begin{bmatrix}-4\\3 \end{bmatrix}[/tex]

- Sales Tax: 9%
What are the roots of the polynomial equation: 4k - 144 = 0 Show all of your work!
Answer:
k = ±6
Step-by-step explanation:
guess your question is 4k²–144 = 0??
4k² = 144
k² = 36
k²–36 = 0
(k+6)(k–6) = 0
k+6 = 0 | k–6 = 0
k = –6, k = 6.
Alternatively; k = ±6.
A triangle with vertices at (1,1), (1,-3), and (3,-3) is acute. In complete sentences, explain whether this statement is true or false, and explain why?
9514 1404 393
Answer:
False; the triangle is "right"
Step-by-step explanation:
The segments lying on lines x=1 and y=-3 make a right angle with each other. The triangle is a right triangle, not an acute triangle.
Martha drew a pair of intersecting non-perpendicular lines, I and m. She numbered one pair of vertical angles <1 and <2, and she labeled the second pair of vertical angles <3 and <4. Martha made the conjecture that <1 =~ <2 to validate this conjecture, which of the following would be appropriate reasoning?
A. M<1+ M<2 +M<3 + m<4 = 360
B. The sum of the measures of angles of a triangle is 180°
C. The measure of all right is 90°
D. Because <1 and <2 are each supplementary to <3, they are therefore congruent
Answer:
D. Because <1 and <2 are each supplementary to <3, they are therefore congruentStep-by-step explanation:
A. m<1 + m<2 + m<3 + m<4 = 360
Incorrect in terms of the proofB. The sum of the measures of angles of a triangle is 180°
Not relevantC. The measure of all right is 90°
Not relevantD. Because <1 and <2 are each supplementary to <3, they are therefore congruent

Find the missing length of the right triangle.
a
21
35
Answer:
28
Step-by-step explanation:
Use the pythagorean theorem and solve for a:
a² + b² = c²
a² + 21² = 35²
a² + 441 = 1225
a² = 784
a = 28
So, the missing length is 28.

Answer:
n = 5 ; n = -1
Step-by-step explanation:
n - 3 = 2
When you transfer (-3) to the other side of the equation, it turns into (+3).
n = 2 + 3
Evaluate.
n = 5
n + 3 = 2
When you transfer (+3) to the other side of the equation, it turns into (-3).
n = 2 - 3
Evaluate.
n = -1

how much is 5 quarters and 8 dimes?
Answer:
205
Step-by-step explanation:
Answer: 2.05 dollars
=================================================
Work Shown:
1 quarter = 25 cents
5 quarters = 125 cents .... multiply both sides by 5
1 dime = 10 cents
8 dimes = 80 cents .... multiply both sides by 8
(5 quarters) + (8 dimes) = (125 cents) + (80 cents) = 205 cents
205 cents = 205/100 = 2.05 dollars
-------------------------
Another way to approach the problem is to compute
5*25 + 8*10 = 205
that's the total number of cents

A cuboid with a volume of 924cm^3 has dimensions 4cm, (x+1)cm and (x+11). Show clearly that x^2+12x-220=0 solve the equation by factorisation, making sure you show the factorisation. Finally, find the dimensions of the cuboid,
Answer:
[tex]x^2+12x-220=0[/tex] -- Proved
[tex]x = 10\ \ \ x = -22[/tex]
Step-by-step explanation:
Given
[tex]Volume = 924cm^3[/tex]
[tex]Dimension: 4cm; (x+1)cm; (x+11)cm[/tex]
Required
Show that [tex]x^2+12x-220=0[/tex]
The volume is calculated as:
[tex]4 * (x + 1) * (x + 11) = 924[/tex]
Open the brackets
[tex](4x + 4) * (x + 11) = 924[/tex]
[tex]4x^2 + 44x + 4x + 44 = 924[/tex]
[tex]4x^2 + 48x+ 44 = 924[/tex]
Collect Like Terms
[tex]4x^2 + 48x+ 44 - 924=0[/tex]
[tex]4x^2 + 48x -880=0[/tex]
Divide through by 4
[tex]\frac{4x^2}{4} + \frac{48x}{4} -\frac{880}{4}=0[/tex]
[tex]x^2+12x-220=0[/tex]
Solving further:
Expand the expression
[tex]x^2 + 22x - 10x - 220 = 0[/tex]
Factorize:
[tex]x(x + 22) - 10(x + 22) = 0[/tex]
[tex](x - 10)(x + 22) = 0[/tex]
Split:
[tex]x - 10 = 0;\ \ \ x + 22 = 0[/tex]
[tex]x = 10\ \ \ x = -22[/tex]
