I need help ASAP!! if you help me you will get 10 pts, and if you can please help explain!

(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°

step-by-step explanation:

first, eliminate the parenthesis:

−

4

x

second, group like terms:

3

−

4

third, combine like terms:

(
