Answer:
Step-by-step explanation:
set 30
1) 90-52 = x
38 = x
2) 90 -15-25=x
50 = x
set 31
1) t = 3m
m = independent
t = dependent

Answer: 103 degrees
Step-by-step explanation:
51 + 26 = 77
A triangle adds up to 180 degrees
180 - 77 = 103
= <u>103 degrees</u>
Answer:
Point B must be at the same distance from the the origin as point A.
Step-by-step explanation:
Coordinates of point A = (3, 3)
When point A is rotated 90° counterclockwise around the origin, coordinates of the new point B will be (-3, 3)
Distance from origin to point A = 
Similarly, distance of point B from the origin = 
Therefore, distances of both the points from the origin are same.
Point B must be at the same distance from the the origin as point A.
