Question

Anyone know how to solve this?

Answer 1

Answer:

b = 22

Step-by-step explanation:

Here b represents the length of the hypotenuse, and 11 is the length of the side opposite the 30 degree angle.  We want to find the value of b.  We use the sine function here because we have the angle measurement (b), the angle 30 degrees and the "opposite side" 11:

sin 30 degrees = (1/2) = 11/b, which, if inverted, is 2 = b/11, or b = 22
