Question

Solve the triangle given 28° angle and adj side of 210

Answer 1

hypotenuse =237.84

opposite =111.66

Explanation:

cos‐¹(210/x)=28

210/x =cos28

210=cos28x

divide by cos28

x=237.84 (hypotenuse)

sin28= x/237.84

x=sin28×237.84

x=111.66 (opposite)

(another way to do it)

Answer 2

Tan(28) = x/210

Explanation:

111.65^2 + 210^2 = hyp^2

opposite = 111.65

hypotenuse = 237.83
