Question

the angles of a triangle are (2×+17) (×+10) and (5×-7).find all the angles of the triangle​

Answer 1

Answer:

we know that

The sum of all angle is =180

A/Q: 2x+7, x+10, 5x-7= 180

8x-10= 180

8x= 180+10

8x= 190

So, x= 190/8= 23.75

Now: the 2x+7= 2×23.75+7=47.50+7 = 54.50

the x+10= 23.75+10= 33.75

the 5x -7=5×23.75-7= 118.75-7= 111.75

So, 54.50, 33.75, 111.75
