Answer:
D
Step-by-step explanation:
This is isosceles triangle
So, y = 53 {angles opposite to equal sides are equal}
53 + 53 + x = 180 {Angle sum property of triangle}
106 +x = 180
Subtract 106 from both sides
x = 180 - 106
x = 74
Answer:
Your answer is D. 74°
Step-by-step explanation:
Your isosceles triangle has a line on its right side and on the bottom, meaning that the top angle is equal to the bottom left side. since all triangles equal 180, you'd add 53+53 to get 106, then subtract 180-106 to get 74. Therefore, X= 74°
I could be wrong since I haven't done this in a long time, but I hope you get it right!
