The** measur**e of the **angles** <C1, <B2 and <B3 are **2x + 10, -2x+80** and ** -2x+80**

A line is defined as the** shortest distance **between two points while an angle is the __point where two lines meet.__

Since the sum of angles on a** straight lin**e is 180 degrees. Therefore;

C<1 + C<2 = 180

**Given** the parameter below;

C2 = 170 - 2x

**Substitute **the given information into the equation

C1 + 170 - 2x = 180

**C1 = 2x + 10**

Also;

C1 + B2 = 90

2x + 10 + B2 = 90

**B2 = -2x + 80**

Since <B2 = B3, hence <B3 = -2x + 80

The** measur**e of the **angles** <C1, <B2 and <B3 are **2x + 10, -2x+80** and ** -2x+80**
