Question

Please help me with this.​

Answer 1

Explanation:

`Sin(45)=(13)/(x)`

This must be the correct equation because sin=p/h. Here, perpendicular(p)=13 and hypotenuse(h)=x. So Sin45=13/x is used to find the value.

Answer 2

d) sin(45°) = 13/
`x`

Explanation:

Trig ratios:

sin(x) = O/H

cos(x) = A/H

tan(x) = O/A

where x is the angle, O = opposite side to angle, A = adjacent side to angle, and H = hypotenuse

From inspection, we have been given the measure of the side OPPOSITE to the angle and the measure of the HYPOTENUSE.

angle = 45°

opposite side = 13

hypotenuse =
`x`

Therefore, substitute these values into the sine trig ratio:

⇒ sin(x) = O/H

⇒ sin(45°) = 13/
`x`
