Question

in triangle pqr,if angle p =2x,angle r =4x and angle q=3x then angle r is equal to
​

Answer 1

Step-by-step explanation:

In ∆ABC, Angle p+ Angle r+ Angle q = 180°

[Angle Sum Property of ∆]

2x + 4x + 3x = 180°

9x = 180°

x = 180°/ 9

x= 20°

Therefore, Angle r = 4x

Therefore, Angle r = 4x =4 × 20°

= 80°

Answer 2

Answer:

In ️ triangle ABC , Angle p+ Angle r+ Angle q = 180°

[Angle Sum Property of A]

2x + 4x + 3x = 180°

9x = 180°

x = 180% 9

x= 20°

Therefore, Angle r = 4x

Therefore, Angle r = 4x 20°

= 80°
