Question

find angle p, q, r .
solve this ​

Answer 1

Answer:

x - 1 + x + 4 + 2x - 3 = 180⁰....( all angles of triangle

are 180⁰)

4x = 180⁰

x = 180

4

x = 45⁰

R = x - 1

= 45 - 1

= 44⁰

Q = 2x - 3

= 2 × 45 - 3

= 90 - 3

= 87⁰

P = x + 4

= 45 + 4

= 49⁰

Answer 2

Step-by-step explanation:

sum of all angles of triangle is 180°

Lp+Lq+Lr =180°

(x+4)+(2x-3)+(x-1)=180°

x+2x+x+4-3-1 =180°

4x+4-4 =180°

x=180/4=45°

Lp=x+4=45°+4=49°

Lq=2x-3=2×45-3=90-3=87°

Lr=x-1=45-1=44°
