What is the the value of x? enter uour answer in the box. 91°, 8x+3°,10x-4°

x = 5 is the right answer.

Step-by-step explanation:

As we know sum of all angles in a triangle is 180°.Therefore in this question we will form an equation.

Sum of all the angles of a triangle = 180

91 + 10x - 4 +8x +3 = 180

90 + 18x = 180

18x + 90 - 90 = 180 - 90

18x = 90

x = 90÷18 = 5

Therefore x = 5 is the right answer.

The value of x is 5

Step-by-step explanation:

In triangle ABC

Using Angle Sum property of triangle to find the value of x.

Angle Sum property: The sum of all angles of a triangle is 180.

Hence, The value of x is 5
