Answer 1

x = 6.6

Explanation:

If the triangles are similar triangles then the side lengths must be proportional.

`(HG)/(JI) = (GK)/(IK)`

• Rewrite the expression using numbers.

`(8)/((x - 1)) = (10)/(7)`

• Cross multiply fractions.

56 = 10x - 10

• Add 10 to both sides of the equation.

66 = 10x

• Divide both sides by 10.

6.6 = x
