Question

if the measures of a triangle are (2x)°,(3x-5)°and (4x-13)° ​

Answer 1

Step-by-step explanation:

When we add, 3 angles than it is supplementary.

Sum of the measure of angles are supplementary, this is the property used in the sum.

So,2x+3x+4x=180.

9x=180.

X=180/9.

X=20.

So,the answer of the question is, the value of x =20 degree.
