(5x+7) + (8x-21) = 90
13x-14 = 90
13x= 104
X=8
The angle measurements are 47, and 43
<span>hmmm: g maps x onto 3-2sin(x) for all x from 0 to A degrees
g(x) = 3-2sin(x)
the inverse would have to be arcsin (3-x)/2, which only has a radian output between -pi and pi i believe. but this is just from memory</span>
The answer is c 10% of 89 is 8.9 so multiply by 3 you get 26.70
0.2,
-0.4,
-4.5
hope this helps
What do u want help with and take it easy btw
