Answer:
a=10
b=37
Step-by-step explanation:
a+5 is equal to the opposite line, 15. 10+5=15 therefore, a must equate to 10
3b is the same angle as 111 therefore 3*b has to equate to 111. 111 divided by 3 equals 37. B has to then equate to 37 to make the proper angle.
Hope my explanation wasn't too confusing, and hope this helps! Good luck!!!
Answer:
-1
Step-by-step explanation:

mean means average total number over frequency
Answer:
The required co-ordinate is (-2, -5).
Step-by-step explanation:
For a given point, reflection of a point (x, y) across a horizontal line y = k, the reflected co-ordinates will be: 
.
Here, (x, y) = (-2, 7) then reflection along the line y = 1, we get:
= (-2, -5)
The reflected point is (-2, -5).
Answer:C
Step-by-step explanation:
I got it right so the answer is C.
Answer:
Step-by-step explanation:
Divide both sides by 1/3, which is equivalent to mulitplying by 3
x - 10 = -12
Add 10 to both sides
x = -2
