To be supplementary the angles must add up to 180°
the two angles must be a linear pair to be supplementary
Answer:
40.374 ft
Step-by-step explanation:
We assume that the height of the goal on the football field is <em>h </em>(ft)
As it can be seen, the height of the goal is equal to the total of the man's height and the length of AB.
=> h = 5.5 + AB
The triangle ABC in the figure is the right angled triangle with Angle B = 90 degree and BC = 10 ft
In a right triangle, we have the equation as following:
+) tan of an acute angle = length of opposite side/ length of the adjacent side
We have: Angle C = 74 is an acute angle, its opposite side is AB, adjacent side is BC
=> tan Angle C = AB/ BC
=> tan 74° = AB/ 10
=> AB = 10. tan 74° = 34.874 ft
=> h = 5.5 + AB =5.5 + 34.874 = 40.374 ft
Four times a number equals negative eight. Hope this helps

Means
sample 1: 3.6
sample 2: 3.3
sample 3: 3.8
Step-by-step explanation:
Three or four times. All of these means are no less than three but no more than four this means that the average number of times is between three or four
