Answer:
∠AOB = 112°
Step-by-step explanation:
mentally draw line segment OC
that line bisects 124° so ∠OCB = 1/2(124°) = 62°
ΔOCB is isosceles because OB = OC
∠OBC = 62° because it is equal to ∠OCB
all triangle interior angles add up to 180°
∠BOC = 180° - 62° - 62° = 56°
∠AOC = 56° because OC was a bisector of ∠AOB
∠AOB = 56° + 56° = 112°

Step-by-step explanation:
Answer:
X = -9
Step-by-step explanation:
y = k X for some fixed number constant k.
-5 = k (15)
k = -5/15 = -1/3
So y = (-1/3)X
When y = 3 ---> 3 = (-1/3)X
X = -9
Answer:
4
Step-by-step explanation:
Decreasing a percentage from a number can be done by multiplying said number and percentage together. That being said:
16 * 25% = 4
Meaning that the result of the number 16 being decreased by 25% is 4
