Question

Find the cosine of each acute angle

Answer 1

cos P = 53 degrees

cos Q = 37 degrees

Explanation:

cos P =
`(adjacent)/(hypothenuse)`

cos P =
`(24)/(40)`

cos P = 0.60

Cos-1 of 0.60 is 53.13 (round to the nearest whole number)

cos P = 53 degrees

cos Q =
`(adjacent)/(hypothenuse)`

cos Q =
`(32)/(40)`

cos Q = 0.80

Cos of 0.80 is 36.86 (round to the nearest whole number)

cos Q = 37 degrees

To check anser:

90 + 53 + 37 = 180

180 = 180
