Answer:
(a) 55
(b) 63
(c) 45
Step-by-step explanation:
All four angles in a rectangle are right angles, so ∠PMN is 90∘.
∠PMN+35∘=90∘
which is the same as saying
∠PMN=90∘−35∘.
Thus, ∠PMN=55∘.
and (b) is the same so:
∠STU is 90°
∠STU = 90° − 27°
∠STU = 63°
and for (c) each angle of a square measure 90°
∠DAB= 90° − 45°
∠DAB = 45°
