Answer:
1. 5 / 6
2. 1 / 3
3. 3 / 6 or 1 / 2
Step-by-step explanation:
The probability that A is not yellow is 5 / 6
The probability that B is blue is 1 / 3
The probability that A is red is 3 / 6 or 1 / 2
Answer:
she bought 5 erasers
Step-by-step explanation:
25-5 is 20 and 20 divided by 4 is 5
Cosine is the ratio of the adjacent side to the hypotenuse.
In short, we have this equation
cos(angle) = adjacent/hypotenuse
In the case of cos(A) = 18/19.5 we can see that
adjacent = 18
hypotenuse = 19.5
The side of 18 cm is next to angle 2, so the 18 cm side is adjacent to angle 2 (in contrast, the 7.5 cm side is the opposite leg in relation to angle 2)
So that's why the answer is angle 2
In other words, replace the '2' angle marker with 'A' to be able to write cos(A) = 18/19.5
Hello!
To find cosine, use the formula cos = adjacent / hypotenuse.
According to angle B, adjacent of angle B is side A, and the hypotenuse is side c because the hypotenuse is always opposite the right angle.
Therefore, the cosine of angle B is a/c.
