How Do You Find a Missing Angle in a Right Triangle?
Find the value of x in the figure.
Summary
- A right angle is an angle measuring 90
° . - A right triangle is a triangle with an angle measuring 90
° . - The measurements of all 3 angles of a triangle add up to 180
° . - Angle D and angle F must be complementary, since together with the right angle A, they add up to 180
° . - Solve for the value of x by subtracting 16
° from both sides to get x by itself.
