Question

What is the value of x?

Answer 1

Hey there!

All of the angles of a triangle add up to 180. We already have 65+79 which is 144. This means only need 36 more degrees to get to 180.

Therefore, your answer is A) 36°.

I hope this helps!

Answer 2

A. 36° is your answer.

Explanation:

Note that the shape given to you is a triangle. The sum of inner angles of a triangle is 180°. Set the equation:

65 + 79 + x = 180

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. First, simplify. Combine like terms:

(65 + 79) + x = 180

(144) + x = 180

Isolate the variable, x. Subtract 144 from both sides:

x + 144 (-144) = 180 (-144)

x = 180 - 144

x = 36

A. 36° is your answer.
