-3x = -3 because you would multiply one of the equations by -1 to eliminate y.

find the area of a square, width times height
then find the area of the triangle, width times height divided by 2
<ACB = 1/2(100 - 42)
<ACB = 1/2(58)
<ACB = 29
answer is A. 29
Answer:
P'(C) = 0.98
Step-by-step explanation:
Given that,
P(C) = 0.02 (The probability of getting C)
We need to find the complement of P(C) i.e. P'(C).
We know that,
P(C)+P'(C)=1
P'(C) = 1-P(C)
= 1-0.02
= 0.98
So, the complement of P(C) is equal to 0.98.
