Question

The angles of triangles are ( x + 30) ,  (2 x − 20) and  ( x + 50) . Find the angles

Answer 1

As we know that sum of triangles is 180 degrees

so,

x+30+2x-20+x+50 =180 degrees

4x-60= 180 degrees

4x=240 degrees

x= 60 degrees

So putting the value of x we get

Ist angle = 90 degrees

2nd angle=100 degrees

3rd angle= 110 degrees

Answer 2

Answer:

60, 40 and 80 degree respectively.

Step-by-step explanation:

Given angles are (x+30), (2x-20) and (x+50).

Therefore,

(x+30)+(2x-20)+(x+50)=180

(Sum of angles in a triangle = 180)

=> 4x + 60 = 180

=> 4x = 180 - 60

=> 4x = 120

=> x = 120/4 = 30

Angle 1= x + 30 = 30 + 30 = 60

Angle 2= 2x - 20 = 60 - 20 = 40

Angle 3= x + 50 = 30 + 50 = 80.

Hope that helps.
