Answer 2

Answer:

Angle NOQ = 90°

Step-by-step explanation:

GIVEN :

Angle PQO =40°

Angle MNO =50°

FIND Angle NOQ?

Solution, :

Construction: Draw a line XY parallel to MN intersecting at pt O.

Now,

MN ll XY ll PQ

Angle PQO = Angle YOQ = 40°...........(1) (ALTERNATE ANGLES)

Angle MNO =Angle YON = 50°.............(2)

(ALTERNATE ANGLES)

ALTERNATE ANGLES: when two parallel lines intersects each other by a transversal, then the resulting angles corresponding to each other are equal.

Angle NOQ = Angle YOQ + Angle YON

= (1) + (2)

= 40° + 50°

= 90°
