Question

Instructions: Find the missing side. Round your answer to the nearest tenth.
33°
16

Answer 1

cos (33)= 16/x

x=19

Answer 2

The value of the missing side x is 19. 07

To determine the value of the longest side which is the hypotenuse of the triangle, we need to know the trigonometric ratio that corresponds to it.

We have the different trigonometric ratios listed as;

• sine
• cosine
• tangent
• cotangent
• secant
• cosecant

Now, we have that;

cos 33 = 16/x

find the value of the identity and substitute

x = 16/0.8386

Divide the value, we get;

x = 19. 07
