Question

What is the measure of AX, in degrees?
N
6
Х
6
70
у

Answer 1

C

Explanation:

Since XY = XZ = 6, then the triangle is isosceles.

The base angles are therefore congruent, that is

∠ Y = ∠ Z = 70°

The sum of the 3 angles in the triangle = 180°, thus

∠ X = 180° - (70 + 70)° = 180° - 140° = 40° → C
