Since opposite exterior angles are congruent I would plug in numbers for X till you find a number that goes into both and gets you the same product.
The answer is C.
You need you use Pythagoras theorem 2 times to have 2 equations with the same sides i.e. for example a2 + b2 = 81 and a2 - b2 = 9.
You can do it as you have different triangles but with the same sides.
The answer to this question is false because it cannot still be both negative after you reflect over two positives.
1] 0.23
2] both are same
3] 20/100 *80= 16
16, with the factors– 1, 2, 4, 8, and 16 itself
