Answer:

a) 24

b) 10

c) 12/13

d) 5/13

e) 12/5

Explanation:

a) We can see that the leg opposite <C is AB, and we are given AB = 24

b) We can see the leg adjacent to <C is AC, and we are given that AC = 10

c) The trig function sine is equal to


(opposite)/(hypotenuse)

The opposite, AB, is 24, and the hypotenuse, BC, is 26. We can plug those numbers in:


sin(c) = (24)/(26) = (12)/(13)

d)The trig function cosine is equal to


(adjacent)/(hypotenuse)

The adjacent, AC, is 10, and the hypotenuse, BC, is 26. We can plug those numbers in:


cos(c) = (10)/(26) = (5)/(13)

d)The trig function tangent is equal to


(opposite)/(adjacent)

The opposite, AB, is 24, and the adjacent, AC, is 10. We can plug those numbers in:


tan(c) = (24)/(10) = (12)/(5)
