Question

determine the value of , if possible. If the triangles are congruent, state which triangle congruence condition you used. If the triangles are not congruent or if there is not enough information, state, “Cannot be determined”.

Answer 1

x = 23.6

Explanation:

Since all the edge angles are 90, if the upper part angle is 35, the lower one in ADC is 90-35 = 65

we now proceed to use the tangent ratio

The tangent ratio is opposite/adjacent

Thus;

Tan 65 = x/11

x = 11 tan 65

x = 23.6
