Answer 1

Answer:

angle NQB= 70⁰ and angle MRQ = 110⁰

Step-by-step explanation:

Here taking the isosceles Triangle PQR,

angle P= 40⁰

Therfore,

Angle PQR + Angle PRQ + 40⁰ = 180⁰(angle sum property)

2x = 180⁰-40⁰

x = 140⁰/2

x = 70⁰

angle NQB = angle PQR = 70⁰

also angle MRQ is supplementary to angle NQB

MRQ = 180-70

= 110⁰
