Answer:
x = -3. Y = 12
Step-by-step explanation:
the answer is D
<u>24</u> = <u>30</u>
x = 100
<u>30x</u> = <u>2400</u>
30 = 30
x = 80
The unlabeled part of the right angle is complementary to 68 degrees, so 22 degrees. y is supplementary to 78 degrees, so 102 degrees. z as the third angle in the small triangle is 180 less than the sum of the other two,
z = 180 - 22 - 102
Answer: 56 degrees
