The measures of two supplementary angles add up to 180 degrees. Therefore, we have the equation: (x + 16) + (3x) = 180.
Combining like terms, we get: 4x + 16 = 180.
Subtracting 16 from both sides, we have: 4x = 164.
Dividing both sides by 4, we get: x = 41.
Therefore, the measure of angle SRT is (3x) = 3 * 41 = 123 degrees.
Two supplementary angles have the following measures: m∠QRS = (x + 16)° and m∠SRT = (3x)°.
What us the measure of ∠SRT?
