Question

HELP NOW 100 POINTS! ABC Is isosceles AB = 88 and CB = 12x +4 X= [?]

Answer 1

x = 7

Explanation:

since the triangle is isosceles then the 2 legs are congruent, that is

CB = AB

12x + 4 = 88 ( subtract 4 from both sides )

12x = 84 ( divide both sides by 12 )

x = 7

Answer 2

x = 7

Explanation:

An isosceles triangle has two sides of equal length.

Given ΔABC is an isosceles triangle, and from inspection of the given diagram:

• BC = AB

Therefore:

`\implies \sf BC=AB`

`\implies 12x+4=88`

`\implies 12x+4-4=88-4`

`\implies 12x=84`

`\implies (12x)/(12)=(84)/(12)`

`\implies x=7`
