Given a = 13, b = 29,

find the missing sides and angles in the right triangle, where a is the side across from angle A,

b, across from B, and

c across from the right angle

Round your answers to three decimal places


c = 31,780, A = ?, B = ?

trying to find A and B
Answered by Steve
c is correct. Now just find A using

sin A = a/c = 13/31.780
once you have A, recall that A+B=90°

for A i got 0.40906 so 0.409 is that correct?
Answered by Steve
No, you want the angle whose sine is .409

Since sin(30°) is 0.5, your angle will be somewhat less than that. Use your calculator. There is probably a 2nd function button, then hit sin. Check whether it is in degrees or radians mode.
