Answer:
133
Explanation:
Supplementary angles are angles that sum to 180°, meaning they form a straight line.
Solving for x
Since we know that these 2 angles will sum to 180 (remember they are supplementary) we can add their expression together and set it equal to 180.
Next, combine like terms.
Add 4 to both sides
Divide by 4
Solve for m∠PQR
Now that we know the value of x, we can find the measure of PQR. Simply plug 46 in for x and solve.
This means that m∠PQR = 133°.
