Question

Please help! what are the angle measures of a and s?

Answer 1

Q = 89
S = 153

Because the two sides are parallel the angles on the two sides of the parallel lines in the shape are co-interior (angles add to 180)

So we can do 180 - 91 = 89 to find angle Q

And 180 - 27 = 153 to find angle S

Hope that helps

Answer 2

Answer:

Q=91, S = 153

Step-by-step explanation:

QR and TS are parallel (see the arrows in the middle?). Means that angles T and Q add up to 180 - they are conjugate angles. Thus Q has to be 89 (since 89+91=180).
Same difference for R and S: they add up to 180 and since one is 27, the other has to be 153.
