Answer:
42.3
Step-by-step explanation:
add both angles then subtract by 180 and the negative number is your answer
Answer:
1/2
Step-by-step explanation:
Simple probability is a ratio of the number of ways the thing we want to happen can to the total possible outcomes.
(For example, we flip a coin and want heads, but it can land on heads or tails. Our probability of getting heads is 1/2, one way to get heads over the 2 possible outcomes)
So for this problem, there's 20 possible things that CAN happen (3 + 7 + 10) and 10 ways we get what we want (a green marble).
Our probability of getting a green marble is
, which simplifies to 
It’s A I think I had it on a recent test :) I’m not sure tho
Hello from MrBillDoesMath!
Answer:
@ = pi/3 (or 60 degrees) or @ = 7 pi/3 (or 420 degrees)
Discussion:
Let "@' denote the angle "theta". We are asked to find @ in the interval [0, 4 pi)
where
4cos(@) - 2 = 0. Adding 2 to both sides
4 cos(@) - 2 +2 = 2 =>
4 cos(@) = 2 Divide both sides by 4
cos(@) = 2/4 = 0.5
This implies that @ = pi/3 (or 60 degrees) or @ = (pi/3 + 2pi) = 7 pi/3 (or 420 degrees)
Thank you,

Answer:

Explanation:
Volume of right rectangular prism is same as volume of cuboid
Length = 22.9 meters
Width = 7.5 meters
Height = 4.6 meters
Volume of right rectangular prism = Length × Width × Height
= 22.9 × 7.5 × 4.6
= 22.9 × 34.5
= 790.05 meter³
= 790 meter³
