Solve for the specified value of the following right triangle.

Question

If A = 34° and a = 55 m, find c.

 

45.60 m

 

98.36 m

 

66.34 m

30.76 m

Answer 1

It is a right triangle with angle C = 90º (assuming standard notation of C the right angle).

So angle B = 90 - 34 =56º.

Now you can use your trig functions to find the third side b and them find c by the Pythagorean formula.

Or pick a different one and find c directly from a trig function.

 

Answer 2

Hmm...I feel like this needs one more piece of info to solve for all parts of the triangle.
