Question

What is the measure of X, in degrees?

A. 40°

B. Cannot be determined

C. 20°

D. 70°

Answer 1

Answer:

A. 40°

Step-by-step explanation:

∠Z=∠Y (base ∠ of isosΔ)

    = 60°

∠X=180-60-60(∠ sum of Δ)

    =40°

Answer 2

Answer:

A

Step-by-step explanation:

z = y                                  Both are opposite equal sides

z = 70                                From the first statement.

y = 70                                Given

x = 180 - z - y                    A triangle has 180 degrees

x = 180 - 70 - 70

x = 40
