This is a true statement.
Consider two events A and B. We say they are complementary if P(A)+P(B) = 1
This means that either event A or event B must happen, since the "1" represents 100% probability. Having a probability of 100% means absolute certainty.
---------
Example:
A = the event it rains
B = the event it does not rain
P(A) = 0.30 = 30% chance of rain
P(B) = 0.70 = 70% chance it does not rain
P(A)+P(B) = 0.30+0.70 = 1
So this shows the two events are complementary.
Answer: 90°
Explanation: the sum of all the angles in a triangle = 180. So 70 + 30 = 90 and 180-90=90
As we know Conversion from fahrenheit to celsius is

We can write it also as

F as y and C as x then we can write it as
2/3 x 3/4 =6/12=1/2
(Multiply numerators, multiply denominators, simplify)
Do 36 divided by the amount of sides the hexagon has. I think I am not sure
