Question

Find c, the hypotenuse, rounded to four decimal places, in a right triamgle with b=16 and B=55 degrees?

a) 11.2033
b) 19.5330
c) 22.6274
d) 27.8951

Answer 1

In order to calculate the value of the hypotenuse we use knowledge on trigonometric functions. For this case, we can use the sine function. We do as follows:

sin 55 = 16 / c
c = 19.5330

Therefore, the correct answer is option B.
