Question

Help! How do I do this??

Answer 1

a = 14.9; b = 11.1

Explanation:

SOHCAHTOA:

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

`cos48`° : adjacent is 10, and hypotenuse is a

`cos48=10/a; a*cos48=10;a=10/cos48`

type 10/cos48 into calculator to get a = 14.9

`sin48`° : opposite is b, and hypotenuse is a

`sin48=b/a; sin48=b/14.9; b=14.9*sin48`

type 14.9*sin48 into calculator to get b = 11.1

Answer 2

a= 10 divided by sin(48)= 13
b=cos(48)x13=9
