Answer:
Step-by-step explanation:
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:
d) sin(45°) = 13/
Step-by-step 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 =
Therefore, substitute these values into the sine trig ratio:
⇒ sin(x) = O/H
⇒ sin(45°) = 13/

Answer:
The horizontal distance from the center is 49.3883 feet
Step-by-step explanation:
The equation of an ellipse is equal to:
Where a is the half of the wide, b is the high of the ellipse, x is the horizontal distance from the center and y is the height of the ellipse at that distance.
Then, replacing a by 106/2 and b by 33.9, we get:
Therefore, the horizontal distances from the center of the arch where the height is equal to 12.3 feet is calculated replacing y by 12.3 and solving for x as:
So, the horizontal distance from the center is 49.3883 feet
