Question

Using the triangle below, which equation can be used to solve for x?

Answer 1

which one of these:
sin 30° = x/15

cos 30° = 15/x

tan 30° = x/15

tan 30° = 15/x

Answer 2

do u have an idea of what trig function you have to use?

Answer 3

no

Answer 4

tan.

Answer 5

tan what?

Answer 6

the sum of the interior angles is 180 degree !
so um

Answer 7

SOH-CAH-TOA

Answer 8

its a right angled
triangle
so two sides are even

Answer 9

opposite length
= adjacent length

Answer 10

SOH: sine=opposite/hypotenuse
CAH: cosine=adjacent/hypotenuse
TOA: tangent=opposite/adjacent

Answer 11

yeah thats the formula

Answer 12

but about the angle ! you need to know the sum of all interior angle is 180 degree

Answer 13

so 90 degree is given

Answer 14

so the other two angles has to be 45 degree

Answer 15

but since the angle is given

Answer 16

tan 30 = x/15

Answer 17

but i don't get how that would solve x?
