Question

Find the length x. round the answer to the nearest tenth

Answer 1

The length of x is 24.7 to the nearest tenth

Using the parameters in the triangle ;

• θ = 39
• opposite side = 20
• Adjacent side = x

Using Trigonometry;

• Tangent = opposite / Adjacent

Inputting the values into the formula;

Tan(39) = 20 / x

x = 20/Tan(29)

x = 24.69

Hence, x = 24.7
