Question

What is the measure of angle x?

Answer 1

55
Explanation: the triangle is equal to 180, 35 plus 90 is 125 and 180-125= 55.

Answer 2

B) 55°

Explanation:

The ∑ of all interior angles of a triangle is 180°.

When you see a square in a angle (as seen in the bottom left of the triangle), it means that it is a right angle, or 90° in measurement.

Set the equation:

180 = x + 90 + 35

First, combine like terms:

180 = x + (90 + 35)

180 = x + 125

Next, subtract 125 from both sides of the equation to isolate the x:

180 (-125) = x + 125 (-125)

x = 180 - 125

x = 55

55°, or B) is your answer.
