Answer

x = 12.2

Step-by-step explanation

In a right-angle triangle, the side opposite the right angle is the Hypotenuse, the side opposite the given angle that is non-right angle is the Opposite and the remaining side is the Adjacent.

So, after noting the three sides in a right triangle, we will then use trignometric ratios to solve for any of the unknown. If the non-right-angle angle given is θ, the trignometric ratios in short forms are written as

SOH, CAH and TOA

SOH means Sin θ = (Opp/Hyp)

CAH means Cos θ = (Adj/Hyp)

TOA means Tan θ = (Opp/Adj)

So, the one to be used depends on the sides of the triangle that are provided.

For this question,

Hypotenuse = ?

Opposite = 14

Adjacent = x = ?

Angle = θ = 49°

TOA means Tan θ = (Opp/Adj)

Tan 49° = (14/x)

Cross multiply

x = (14/Tan 49°)

Tan 49° = 1.1504

x = (14/1.1504)

x = 12.2

Hope this Helps!!!
