Answer:
The answer would be option A. h = –7, h = 21
Step-by-step explanation:
Question: -2 |h-7|=-28
Substitution: -2 |-14 (-7-7)| = -28
-2*14=-28
Substitution 2:
-2 |14 (21-7)|=-28
-2*14=-28
4(4x+10)=360
16x+40=360
-40 -40
16x=320
÷16 <span> ÷16
</span>
x=20
Cos = adj/hyp
hyp = AB
cos(25) = 7/AB
AB = 7.7
