Please Help for both 6 and 7. I’m confused on both. Please show Explanation. Will Select Brainliest.
krek1111 [17]

answer: 32, 72

question 6

angle PQR and 148 are supplementary angles, so they add up to 180

PQR + 148 = 180

PQR = 180 - 148 = 32

question 7

in triangle RTS, all three angles must add up to 180

angle R = angle PQR = 32

angle S = 180 - 104 = 76 (because of supplementary angles)

angle T = angle RTS (we need to find this)

32 + 76 + angle RTS = 180

angle RTS = 72
