Answer:

Part A - D:8

Part B - C:140°

<h3>Solving/Reasoning:</h3>

Part A: Vertical angles are always congruent.

Part B: If angles are supplementary, they need to equal 180 when added together. Since we know angle A is 40, we can subtract it from 180 and figure out what is left over that should be angle B.

40+B=180

B=180-40

B=140

Find the measure of the segment indicated.
julsineya [31]
Answer is QM = 18

You can find the length of QM by using Pythagorean theorem. See the attachment.

It is a quadrilateral with 4 equal congruent sides.

If SP = 30, so do the other 3 sides indicated by the tick marks on all 4 sides.

We will call side RQ = the hypotenuse
or side “c” = 30
We know RM is leg “b” = 24
Side “a” is our unknown QM

Our formula is
a^2 + b^2 = c^2

a^2 + 24^2 = 30^2

a^2 + 576 = 900

a^2 = 900 - 576

a^2 = 324

Take square root of both sides to solve a

a = 18

QM = 18
