Answer:
The angle measures approximately 18.19°.
Step-by-step explanation:
Since we want to find the angle and we are given the side adjacent to the angle and the hypotenuse, we can use the cosine ratio. Recall that:
The adjacent side is 19 and the hypotenuse is 20. Substitute:
We can take the inverse cosine of both sides:
Use a calculator (make sure you're in Degrees Mode!). Hence:
The angle measures approximately 18.19°.
Answer: 25%
Step-by-step explanation: To write a fraction as a percent, first remember that a percent is a ratio of a number to 100. if we want to write 1/4 as a percent, we need to find a fraction equivalent to 1/4 with a 100 in the denominator. We can do this by setting up a proportion.
=
4n = 100
÷4 ÷4
n = 25
Therefore, 1/4 is equivalent to 25%.
