Question

Show work to determine the value of x.

Answer 1

ok so since the total measurement is 180° and you know that 1 of the sides is 40° and the other 2 are the same you will just need to subtract 40 from 180 and split that in half

here's the formula

`(180 - 40) / 2 = \\ 140 / 2 = \\ 70`

therefore

x=70°
