Question

State the value of the length or ratio based on the triangle pictured.

10. length of side opposite ZA
21
20
B
12. length of hypotenuse
14. cos A
11. length of side adjacent ZA
13. sin A
15. tan A

Answer 1

see explanation

Explanation:

10

length of side opposite ∠ A is BC = 20

11

length of side adjacent to ∠ A is AC = 21

12

length of hypotenuse is AB = 29

13

sin A =
`(opposite)/(hypotenuse)` =
`(20)/(29)`

14

cos A =
`(adjacent)/(hypotenuse)` =
`(21)/(29)`

15

tan A =
`(opposite)/(adjacent)` =
`(20)/(21)`
