Find all six trigonometric ratios of beta Simplify and ratio

Find all six trigonometric ratios of beta. Simplify and rationalize all denominators Answers only on page 1. sin beta = cos beta = tan beta = cot beta = csc beta = sec beta = Find the value of c. Round to the nearest hundredth. C = Use a calculator to find the following values. (Round to the nearest thousandth.)

Solution

1)opposite side²+adjacent side²=hypotenuse²

7²+x²=21²

x=392

x=142

sin=7/21=1/3

cos=(142)/21 =(22)/3

tan=7/(142) =1/(22)=(2)/4

cot=(142)/7 =22

csc=21/7 =3

sec=21/(142) =3/(22)=(32)/4

2)cos(32^o41\'28\")=65.1/c

cos(32+(41/60)+(28/3600))^o=65.1/c

cos(32.691)^o=65.1/c

0.8416 =65.1/c

c=65.1/0.8416

c=77.35
