Answer:
38 degrees
Step-by-step explanation:
Since the degrees in a triangle add up to 180, all you need to do is to find the other 2 angles in the triangle and subtract their sum from 180. Since you have the exterior angles, you can just find their supplements to get the two missing angles.
180-134=46
180-84=96
180-(46+96)=38
21/22
use y2-y1 / x2-x1
(9-(-12)) / (3-(-19))
21/22
Answer:
it is 30.5
Step-by-step explanation:
(3X+4Y):2
(3×7+4×10):2
(21+40):2
61:2
30.5
14 days = 2 weeks
20weeks : 14 days = 20 weeks : 2 weeks = 20 weeks / 2 weeks = 10:1
