since its an isosceles triangle, the other two angles will be the same

OpenStudy (lgbasallote):

it's an isosceles triangle so the base angles are equal 64 + 2x = 180 solve for x

OpenStudy (anonymous):

64 + 2x = 180 2x = 180 - 64 x= 116/2 x=58

@lgbasallote , is it right?

OpenStudy (lgbasallote):

yup

OpenStudy (lgbasallote):

58 + 58 + 64 =180 so you're right
