Answer:
Step-by-step explanation:
We know that the sum of Angle S and Angle T is 120. So:
The measure of Angle S is (4x + 30).
And the measure of Angle T is (30).
We want to find the value of <em>x</em>.
By substitution:
Combine like terms:
Subtract 60 from both sides:
Divide both sides by 4:
Hence, the value of <em>x </em>is 15.
