Question

What is the measure of angle x?

Answer 1

X = 180 - (90 + 47)
x = 180 - 137
x = 43

answer angle x = 43

Answer 2

The angle of x is equal to 43°

As we know, any straight line would have an angle of 180°. Also, when we see the right angle symbol (the box in the top left quadrant of the graph), that means the angle is exactly 90°. We are also given an angle of 47°. We can now set up an equation with the numbers we have.

90° + 47° + x = 180°

This basically says that all three of the angles we listed make up that straight line which would equal 180°. Let's work this down to our answer:

137° + x = 180°.........................................Add 90° & 47°

x = 43°.....................................................Subtract 137° from both sides

I hope this helped!! Have an amazing day :))
