U/72 = 2/4
means u/72 = 0.5
therefore u = 72*0.5
which equals 36
Answer:
67
Step-by-step explanation:
Complementary angles add to 90 degrees
<A + <B = 90
x+10 + 3x+28 = 90
Combine like terms
4x+38 =90
Subtract 38 from each side
4x+38-38 = 90-38
4x = 52
Divide by 4
4x/4 = 52/4
x = 13
We want to find <B
<B = 3x+28
= 3(13) +28
= 39+28
=67
3v+1=6v-8
1+8=6v-3v
9=3v
9/3=v
Plug 3 into the expression to solve and you get 10.
It’s 20 I believe. All together it should be 160 so you add 118 and 22 to get 140. Then subtract that from 160 and you get 20.
Im confidence that the answer is C cuz im in middle school but im a nerd
