Question

How do I solve this??

Answer 1

Step-by-step explanation:

On the straight line where x is located on, we can identify that the line is equal to 180⁰.

180⁰ = 125⁰ + 30⁰ + x⁰

Find the value of x.

$180 = 155 + x$

Subtract 155 from both sides:

$25 = x$

The unknown measurement (x) equals 25⁰.
