Question

the angle of a triangle are 2x, (3x-5) and (4x-13) then find the value of x

Answer 1

Step-by-step explanation:

2x+3x-5+4x-13=180°(sum of angles)

9x-18=180°

9x=180°+18°

9x=198°

x=198÷9

x=22°

2x=2(22)=44°

3x-5=3(22)-5=66°-5°=61° 4x-13=4(22)-13=88°-13°=75°

Answer 2

The correct answer is 22°.

Given: Angles of triangle = 2x, 3x-5, 4x-13.

To Find: Value of x.

Solution:

As we know that sum of angles of triangle is 180°.

2x + (3x - 5) + (4x - 13) = 180°

9x - 18 = 180

9x = 198

x = 22°

Hence, the value of x is 22°.
