Answer:
36°
Step-by-step explanation:
The computation of the measure of the angle is shown below:
As we know that
The trigonometric function in the right angle is
sinα = OS ÷ H
And,
cosα = AS ÷ H
Here
α represent the one of the angles
OS and AS represent the opposite sides
And, H represent the hypotenuse
So
sinx = 8.5 ÷ 14.5
x = arcsin = 8.5 ÷ 14.5
= 35.88
= 36 degrees
Answer:
10% because you are supposed to didvide 2 by 20 to find the percentage
Answer: P = 3/10
Step-by-step explanation:
Given: The total number of marbles - 5 + 2 + 3 = 10
The number of black balls = 2
Then the number of balls which are not black 10 - 2 = 9
Then the probability of not drawing a black marble is given by
P(Not Black) = Not black = 8/10 = 4/5
-------------
Total
The number of red marbles = 3
Then the probability of drawing a red marble is given
P(Red) = Red = 3/10
------
Total

they're at a 3:1 ratio, thus, 3 times.
