Question

CAN ANYONE HELP ME WITH QUESTION 6

Answer 1

SINCE THATS AN ISOSCELES TRIANGLE:

AB=BC

SO 3x-4=5x-10

But we have to find x

3x-4=5x-10

Minus 3x on both sides

-4=2x-10

Add 10 on both sides

6=2x

Divide 2 on both sides

3=x

So x is 3

Now since we are looking for side AB which is 3x-4

Substitute in 3 as x

3(3)-4

9-4=5

So 5 is the answer.

Brainlist would be much appreciated!
