Answer:

x = 22°

∠PQS = 112°

∠SQR = 68°

Step-by-step explanation:

        Since ∠PQR is a straight angle, it is equal to 180°. This means that ∠PQS and ∠SQR added together is also equal to 180°.

        ∠PQS + ∠SQR = 180°

        (6x - 20) + (3x + 2) = 180°

        6x + 3x + 2 - 20 = 180°

        9x - 18 = 180°

        9x = 198°

                 x = 22

        Now, we can substiute x into ∠PQS and ∠SQR.

        ∠PQS

        (6(22) - 20)

                 ∠PQS = 112°

        ∠SQR

        (3x + 2)

        (3(22) + 2)

                 ∠SQR = 68°

Answer:

x = 22

PQS = 112

SQR = 68

Step-by-step explanation:

Straight angles equal to 180 degrees

(6x - 20) + (3x + 2) = 180

9x - 18 = 180

9x = 198

x = 22

I'm pretty sure the answer is D. because I don't think anyone would want to take their total meal cost and then multiply it by their tip to make it even larger. You would just add the tip to the meal cost.
