Question

What is the value of x in the figure?

Answer 1

x = 50

Explanation:

From the diagram, we know that angle (x + 10)° and angle 30° are complementary angles (they add up to 90°). From this information, we can create the following equation.

(x + 10)° + 30° = 90°

x° + 10° = 90° - 30°

x° = 60° - 10°

x° = 50°

x = 50

Answer 2

The total angle is 90° (A quadrant)

x+10 + 30 =90

x= 90-40

x=50°
