Answer:

Explanation:

1). By applying cosine rule in the given triangle,

cos(x°) =
\frac{\text{Adjacent side}}{\text{Hypotenuse}}

cos(x°) =
(6)/(8)

x =
\text{cos}^(-1)((3)/(4) )

x = 41.41°

2). By applying cosine rule in the given triangle,

cos(x°) =
\frac{\text{Adjacent side}}{\text{Hypotenuse}}

cos(x°) =
(4)/(5)

x =
\text{cos}^(-1)(0.8)

x = 36.87°

3). By applying cosine rule in the given triangle,

cos(x°) =
\frac{\text{Adjacent side}}{\text{Hypotenuse}}

cos(x°) =
(51)/(85)

x =
\text{cos}^(-1)(0.6)

x = 53.13°
