Question

What is the value of x ?

Answer 1

Answer:

B) 63 degrees

Step-by-step explanation:

All triangles equal up to 180 degrees so you would subtract the lengths you are given by 180.

So 180 - 54 = 126

Now you would divide 126 by 2 since this is an isosceles triangle. Isosceles triangles have two equal sides so 126 divided by 2 equals 63 degrees.

So y = 63 degrees

Answer 2

the answer is 63 because 63*2=126 and 126+54=180 and all triangles add up to 180
