Answer:
'Can't give a proper answer with no shown data so....
Step-by-step explanation:
1. cos63=x/16
x=16cos63
x=7.3
= 56°
= 34°
3x + 5 + 2x = 90°
3x + 2x + 5 = 90°
5x + 5 = 90°
5x = 90 - 5
5x = 85
x = 85/5
x = 17
3x + 5
= 3(17) + 5
= 51 + 5
2x
= 2(17)
ok so i think it it a or b i don't know but hope i am right
