Find the values of x and y.<br> No calculator needed.<br> Leave ✓ as a part of your answer.
valentina_108 [34]

Answer:

y=6 x=8.49

Step-by-step explanation:

Since angles p and r are 45deg QP and QR are the same length.

the pythagorean theorem states that a^2+b^2=c^2.

so 6^2+6^2=72

the square root of 72 is 8.49.

so x or c = 8.49

What is the measure of angle C rounded to the nearest whole number?
Rufina [12.5K]
The measure of angle C is 45°.

First, you must know that a triangles angles add up to 180°.

Then, do 180° - 90° = 90° because there is a right angle and right angles are equal to 90°.

Next, you need to split the 90° into 2 because there are 2 remaining angles. 90/2 = 45

Therefore C = 45°

Answer:

\huge\boxed{Answer\hookleftarrow}

15b - 6 - 3b + 10 \\ 15b - 3b - 6 + 10 \\  = 12b  + 4

12b + 4 is in the form nb + m, where,

  • <u>n = 12</u>
  • <u>m = 4</u>

So,

= n + m \\  = 12 + 4 \\  = 16

✐ <u>1</u><u>6</u><u> </u>is the correct answer.
