Question

in desperate need of help! will someone just please help
find x

a. 9
b. 18
c. 9sqrt3
d. 3sqrt3

Answer 1

@katlin95 - What's sin 30 here?

Answer 2

ratios of a 30 - 60 - 90 right triangle are \(1:\sqrt{3}:2\) for
short leg : long leg: hypotenuse
you have the short leg is 9 so the long leg is \(2\times9=18\)

Answer 3

the problem is the picture sucks.
the 30 degree angle is half of the 60 degree angle so it should look like this

Answer 4

whoever drew the picture did not know what they were doing
you cannot make a 30 degree angle the same size as a 60 degree angle
the 60 degree angle is twice as big
