Answer:
x = 48 degrees
Step-by-step explanation:
This is an isosceles triangle because two sides of the triangle are marked equally
so it means the two bottom corners of the triangle (the 66 degrees and the bottom angle on the right) are equal (1)
The theorem says that all the angles in a triangle adds up to 180 degrees (2)
(1), (2) =) 180 - 66*2 = 48 degrees
x = 48 degrees
I hope this help^^ Sr if I make any mistake in the grammar
