Answer:
4)x=15
5)137 degrees
6)supplementary
7)complentary
8)neither
Step-by-step explanation:
4) complementary angles sum = 90
so (3*15+30)
45+30=75
angle 1+angle 2=90
angle 1+75=90
90-75=15
angle1=15
5) angle z is a linear angle which means angle43+anglez=180
180-43=137 degrees
6) supplementary angles =180 degrees
53+127=180
so these angles are supplementary
7) complementary angles =90
56+34=90
so these angles are complementary
8) angles are vertical
HOpe this helps plz vote my answer the brainiest if it does!!!

A.
By using distributive property you can figure out all the answers.
A: 4*3a, 4*2= 12a + 8
B: 4*3a, 4*8= 12a + 32
C: 6*6a, 6*2= 36a + 12
D: 6*6a, 6*8= 36a + 48
Answer:Answer:
8
Step-by-step explanation:
10(8) + 20 = 120
15 (8) = 120
