Question

Can someone help this one is really throwing me off? Thanks

Answer 1

These given angles are vertically opposite which means their measure is equal. Let's find x with the help of the equation..~

$\sf3x - 5 = 145$

Move the constant to the right-hand side and change its sign

$\sf \: 3x = 145 + 5$

Add the numbers

$\sf \: 3x = 150$

Divide both sides of equation by 3

$\boxed{ \tt \: x = 50}$
