X is 50 because a triangle should end up being equal to 180 in total and since the top is 80 then that leaves you with 100 and then the two bottoms are the same so that makes it 50

Answer:

x = 50

Explanation:

The base angles of an isosceles triangle are the same

The unmarked angle is also x

The sum of the angles of a triangle is 180

x+x+ 80 = 180

2x+80 =180

Subtract 80 from each side

2x+80-80 = 180-80

2x = 100

Divide by 2

2x/2 = 100/2

x = 50
