I do believe the answers in a row are A: x, B: 40, C: 12, D:y
#1: 4*5 + 4*6=20+24=44
#2: 4*(5+6)=4*11=44
Answer:

Step-by-step explanation:
we know that
An isosceles triangle has two equal sides and two equal angles

In this problem the triangle ABC is an isosceles triangle
so



The sum of the internal angles of a triangle is equal to 
so
Find the value of y
