Question

In Fig. 3.14 , find MPN​

Answer 1

Answer:

150°

Step-by-step explanation:

sum of all interior angles in a qudrilateral = 360°

therefore

angle MPN = 360° - ( 90° + 90° + 30°)

angle MPN = 360° - 210°

angle MPN = 150°

Answer 2

Answer:

it has 4 sides so it is a quadrilateral

we know that the sum of all interior angles of a triangle is = 360⁰

i.e ∠w+∠x+∠y+∠z =360⁰

Step-by-step explanation:

let ∠MPN be x⁰ then

90⁰+90⁰+30⁰+x⁰= 360⁰

=> 180⁰ + 30⁰ + x⁰ = 360⁰

=> 210 ⁰ + x ⁰ = 360⁰

=> x⁰ = 360⁰ -210⁰

=> x⁰ = 150⁰

∠MPN = ∠X = 150⁰
