Answer:
so 2x+3x+130=180
so 5x+130=180
5x=50
so 2x =20
3x which is angle a is equal to 30 degree
Answer: 12
Step-by-step explanation:
If you look at the image below, you will see a picture of a dodecahedron. We can see 6 sides, and there are 6 sides invisible to our view. 6+6=12
The answer is 12.
<span>2 3/4 = 2.75
so
</span>2 3/4 = 2.75%
x = 12 , y = 18 (12, 18) is the solution, intersection of the two lines.
Answer: 14 / 20 = 70%
