Question

2 multiple choice 25 points if a = 80 solve for x. si a = 80 resolver para x. triangle diagram with angles a and x at base, options 50, 90, 80, 100 previous

Explanation:

Step1: Identify triangle type

The triangle is isosceles (two equal base angles), so \( a = x \) if base angles, but wait—wait, no, wait. Wait, actually, the triangle has two equal angles at the base, so if one base angle is \( a = 80 \), the other base angle \( x \) should be equal? Wait, no, maybe I misread. Wait, the triangle is isosceles with two equal sides, so the base angles are equal. So if \( a = 80 \), then \( x = 80 \)? Wait, but let's check. Wait, maybe the triangle is isosceles, so the two base angles are equal. So \( a = x \), so if \( a = 80 \), then \( x = 80 \). Wait, but let's confirm. The diagram shows a triangle with two equal angles at the base, labeled \( a \) and \( x \). So in an isosceles triangle, the base angles are equal. So \( a = x \). Given \( a = 80 \), so \( x = 80 \).

Step2: Confirm the value

Since the triangle is isosceles (two equal base angles), \( a = x \). Given \( a = 80 \), so \( x = 80 \).

Answer:

80 (corresponding to the option "80")
