I need help with my trig homework

1. sine = opposite / hypotenuse = 30 / 34 = 15 / 17

cosine = adjacent / hypotenuse = 16 / 34 = 8 / 17

tangent = opposite / adjacent = 30 / 16 = 15 / 8

2. you have to use the law of sines function

the formula for law of sines is

sin of angle A / side A  =  sin of angle B / side B  =  sine of angle C / side C

The information we know is sin of a and side a which is 90 degrees and side A length of 20

we don't know Side B and C

we know sin of angle B = 45 degrees

all we have to do is ratios

now divide both sides by sin(90

left side both cancel and on right side 14.14/ sin(90 = 14.14 is the answer
