Answer 1

Answer:

Step-by-step explanation:

We know that

[ Total angle of triangle = 180° ]

Therefore,

(x+10)+(x+40)+(2x-30)=180

↪4x +20=180

↪4x = 160

↪x = 160/4

↪x = 40

The angles of the triangle are

(x+10) = 40+10= 50°

(x+40) =40+40= 80°

(2x-30)= 2*40-30=80-30= 50°

(50+80+50=180)

Answer 2

Answer:

x+10+x+40+2x-30 = 180⁰ (angle sum property of triangle)

4x+20 = 180⁰

4x = 180⁰-20⁰

4x = 160⁰

x = 40⁰

angles are (x+10) = 40+10 = 50⁰

(x+40) = 40+40 = 80⁰

(2x-30) = 2×40-30 = 50⁰
