# How to find the missing angle of a triangle?

#### Understand the Problem

The question is asking how to calculate the missing angle in a triangle when the other two angles are known. This can be done using the fact that the sum of the angles in a triangle is always 180 degrees.

70 degrees

The final answer is 70 degrees

#### Steps to Solve

1. Determine the sum of the angles in a triangle

Each triangle has three angles, and the sum of these angles is always 180 degrees.

1. Identify the known angles in the triangle

Assume the two known angles are $\theta_1$ and $\theta_2$. Let's call the missing angle $\theta_3$.

1. Set up the equation

Since the sum of the three angles must equal 180 degrees: $$\theta_1 + \theta_2 + \theta_3 = 180$$

1. Solve for the missing angle

Rearrange the equation to solve for $\theta_3$: $$\theta_3 = 180 - \theta_1 - \theta_2$$

1. Substitute in the known values

If $heta_1$ and $heta_2$ are known, plug them into the equation to find $\theta_3$

For example, if $heta_1 = 50^\ ext{\ -ted} heta_2 = 60^\ ext{\ -ted}$: $$\theta_3 = 180 - 50 - 60 = 70$$

The final answer is 70 degrees
