If you plug in 90 into theta, the expression becomes sin(180), which has a value of zero. Therefore 90 cannot be a solution to this equation. Hope this helps.
The answer to this question will be E
I would add the two degrees you have then subtract that from 180 so you have
Z=107
Answer:
4×5
3×2
Step-by-step explanation:
a+b=8 or a=8-b
4a+2b=26
4(8-b)+2b=26
32-4b+2b=26
32-2b=26
32-26=2b
6=2b
b=3
a=8-3
a=5
