Question

What is the value of x ?

Answer 1

25

Explanation:

180-(21+73+51)=25

Answer 2

Hey there! :)

Answer:

C. m∠x = 35°.

Explanation:

Begin by finding the value of the third angle of the triangle. Recall that all interior angles of a triangle sum up to 180°:

180 - 73 - 51 = 56°.

Since the top angle is split into x and 21°, simply subtract to solve for x:

56 - 21 = 35°. Therefore:

m∠x = 35°.
