Can somebody me with questions 27 and 28?

check the picture below.

27)

since those angles on the other side, are alternate interior angles, then ∡RST = 110°.

28)

for the same reason, those angles on the outside are alternate interior angles to 110° and 120°, and those angles outside are linear angles with the ones inside, recall linear angles add up to 180°.

therefore ∡RST = 130°.

$9.41
