Question

The angle of a triangle are (x-5)°, (x+15)° and (2x-30)° .Find the angle.​

Answer 1

Answer:

45°, 65°, 70°

Step-by-step explanation:

(x-5°)+(x+15°)+(2x-30°) = 180°

4x+15-35=180

4x=180+20

4x=200

x=200/4

x=50°

First angle = (x-5)° = 50-5 = 45°

Second angle = (x+15)° = 50+15 = 65°

Third angle = (2x-30)° = (2*50-30) = 100-30 = 70°

Answer 2

Answer:

Angles are 45 degree, 65 degree and 70 degree

Step-by-step explanation:

We know that the sum of angles of a triangle is 180 degrees.

So. (x-5) + (x+15) + (2x-30) = 180

=> x-5+x+15+2x-30 = 180

=> 4x - 20 = 180

=> 4x = 180+20

=> x = 200/4

=> x = 50

Now, x-5 = 50-5 = 45 degree

         x+15 = 50+15 = 65 degree

         2x-30 = 2*50-30 = 100-30 = 70 degree
