Answer:

13.5

18.1

72.2

12.8

6,2

66.1

49.1

14

31.8

Step-by-step explanation:

In solving this question, remember the annotation SOHCAHTOA

1. We are given the value of the hypotenuse and we are to determine the value of the adjacent side. COS would be used to determine this value

Cos 26 = Adjacent / hypotenuse

cos 26 = x / 15

x / 15 =0.8988

x = 15 x 0.8988 = 13.5

2. We are given the value of the hypotenuse and we are to determine the value of the opposite side. SIN would be used to determine this value

Sin = opposite / hypotenuse

sin 49 = x / 24

0.7547 = x / 24

x = 0.7547 x 24

x = 18.1

3. We are given the value of the opposite side and we are to determine the value of the adjacent side. TAN would be used to determine this value

Tan = opposite / adjacent

tan 14 = 18 /x

18 / 0.2493 = 72.2

4.  We are given the value of the adjacent and we are to determine the value of the hypotenuse side. COS would be used to determine this value

cos 67 = opposite / hypotenuse

0.3907 = 5/x

x =5/  0.3907 = 12.8

to determine the missing angle

7. tan^-1 = opposite / adjacent

8. cos^-1 = adjacent / hypotenuse

9 = sin^-1 = opposite / hyotensue
