Tan x°= Opposite/ adjacent<span>so tan </span>x°=86
When two angles are supplementary, that means that the sum of their individual angles is equal to a straight line, which is 180°. If you add another restriction where the two supplementary angles are equal, then each vale of the angle constitutes half of 180°. Then, that means that ∠A = ∠B = 90°. The answer is C.

Answer:
5 (cm)
Step-by-step explanation:
1. according to the condition in ΔABC: AC=BC, m∠C=90°. Then m∠B=m∠A=45° and
2. x=AC=AB/√2; ⇔ x=5 (cm).
