Question

Ona piece of paper usa protracter to construct right trangle ABC with AB = 4in. , m∠A90°, and m∠B= 45°
What statement is true about the triangle?

AC = 2 in.

BC = 8 in.

AC = 4 in.

BC = 4 in.

Answer 1

Answer:

AC = 4 in.

Step-by-step explanation:

Since m∠A = 90° and m∠B = 45°, you know that m∠C = 45° ( because you can tell it's an isosceles right triangle ).

This means that legs AB and AC both have to be congruent.

If leg AB is 4 in, then leg AC is 4 in.
