Multiply both sides by the reciprocal (-8/7). You would get 40/7 or 5.71428571
B 2/10 is not simplified because you can divide each number by 2 reducing it to 1/5.
J: 1/12
m: 1/12
i think this is the answer. hope it helps :)
The total measure of all the angles in a triangle is 180°.
Since there is already a 90° angle, the other 2 angles must also add up to 90°.
The only answer that fits is x = 9.
Check:
9x7 = 63°
3x9 = 27°
Add up = 90°
