Solve for $x$ in each diagram below.

The Triangle Angle Sum Theorem states that the sum of
all the interior angles in a triangle will be $180^\circ$.
Find the missing angle in each triangle.

The sum of supplementary angles is $180^\circ$.
Solve for $x$ using the general equation
missing angle $+ x = 180^\circ$.

1. $x = 110^\circ$

1. $x = 70^\circ$
