Question

Can someone tell me the answer to this please..?

Answer 1

x=8

this is because you do 57+89=146

and then you do 180-146 because a triangle adds up to 180.

this gives you 34

so the value of 5x-6=34

add the 6 onto 34 which gets rid of the -6 ans fives you the answer of 40

After that yoy divide 40 by 5 which gives you the value of x which is 8
