Question

If the measure of the angle of a triangle are (2x - 5) , (3x - 1/2) and ( 30 -x/2) ,then x =
​

Answer 1

Step-by-step explanation:

sum of the angles in a triangle are : 180°

(2x - 5 ) + ( 3x - ½ ) + ( 30 - x/2) = 180

2x - 5 + 3x - 1/2 + 30 - x/2 = 180

5x - x/2 = 180 - 30 + 5 + 1/2

[2(5x) - x]/2 = 155 + 1/2

(10x - x)/2 = [2(155) + 1] /2

9x/2 = 311/2

x = (311 × 2)/(9 × 2)

x = 311/9

Answer 2

The ans is 311/9
