Question

Find x and y in simplest radical form.

Answer 1

do you know the trigonometric functions ?

Answer 2

no, I'm in geometry

Answer 3

yes these are used in geometry

Answer 4

oh oops, but no

Answer 5

sin,cos,tan and cot - you dont learned it ?

Answer 6

nope, its an online course

Answer 7

but without these you not can solving it

Answer 8

oh

Answer 9

because you know in this case this angle measure of 30 degrees and to find the y value you can using sin30 = 5/y and than you know that sin30 = 1/2 so you get

1/2 = 5/y cross multiple and will get

y = 10

right ?

Answer 10

yes

Answer 11

so and now than you know the lenght of two sides and bc. this is a right triangle so you can using pythagora"s to find the 3rd unknowed length of side

yes ?

Answer 12

so 100+25=x2

Answer 13

no

bc. than you see the 10 is the length of hypotenuse so what say the pythagora's ?

Answer 14

oh so x2+25=100

Answer 15

yes

Answer 16

this is where i always get stuck i get to x2=75 and don't know what to do

Answer 17

x^2 = 75

x^2 = 3*25

x^2 = 3*5^2

x = sqrt(3*5^2)

x = ?

Answer 18

so 15?

Answer 19

wait no

Answer 20

5 square root 3

Answer 21
