The answer is A and B. I showed my work below. I hope it makes sense. Let me know if you have any questions.
Answer:
hi it's
Easy B
Step-by-step explanation:
No Problem
Step-by-step explanation:
The value of all the angles in a triangle add up to 180.
So to find x do 180-(66+52)
The angle opposite of x is the same value as x
X+E or X+Z are both equal to 180.
So the given angles are supplementary (add to 180). You take the two and add them. 21x+5+37x+1. This gets set to equal 180. 58x+6=180. Subtract 6 from both then divide by 58. You get x=3
Simplified it's 576x^8y^7
