Question

Construct a ∆PQR whose perimeter is equal to 14 cm, ∠P = 45° and ∠Q = 60°. Give

justification​

Answer 1

Answer:

Answer=>75°

Step-by-step explanation:

We know that the sum of a triangle is 180°

∆R we take x

∆PQR=180°

45°+60°+x=180°

105°+x=180°

By transposing

x=180°-105°

x=75°

Answer 2

Answer:

Answer:

Answer=>75°

Step-by-step explanation:

We know that the sum of a triangle is 180°

∆R we take x

∆PQR=180°

45°+60°+x=180°

105°+x=180°

By transposing

x=180°-105°

x=75°
