Question

What is the value for x?

Answer 1

y=10

x=5

Step-by-step explanation

The base angles of an isosceles triangle are equal.

This implies that:

8y-7=73°

Add 7 to both sides:

8y=73+7

8y=80°

y=10°

Interior angles of a triangle sums up to 180°

73+73+6x+4=180

150+6x=180

6x=180-150

6x=30

Divide both sides by 6

x=5
