You know angles B and C are both 60°, the values of the angles in an equilateral triangle. Since the sum of angles in a quadrilateral is 360°, you have
B + C + x + y = 360°
60° +60° + x + y = 360°
x + y = 240°
Answer:
12
Step-by-step explanation:
Your ratio is 24:8. This ratio simplified is 3:1. 4x3=12. x=12.
The answer should be 2d-20.
Need an explanation?
