this is an isoscele triangle, AB = BC, and the angle A is equal angle C.
8y - 7 = 73
8y = 73 + 7
8y = 80
y = 80 : 8
y = 10
------------------------
the sum of the interior angles is 180°
180 - 73 - 73 = 34° (angle B)
6x + 4 = 34
6x = 30
x = 30 : 6 =
x = 5
since this is an isosceles triangle, angle a =angle c
73 = 8y-7
add 7 to each side
80 = 8y
divide by 8
y =10
the sum of all three angles =180
<a +<b+<c = 180
73+6x+4 +73 = 180
add like terms
150 +6x = 180
subtract 150 from each side
divide by 6
x=5
