1st :The angle of depression 30° = the angle of elevation (from the truck to the height of the building.
2nd :
cos 30° = (adjacent side)/(hypotenuse)
cos 30° = x/100, but cos 30°= (√3)/2
(√3)/2 = x/100 and x = (100√3)/2
and x = (50.√3) = 86.60 m
Answer:
90%
Step-by-step explanation:
Complimentary means the same. And adding them together would equal 90. Just as you would divide 90 by 3, each individual angle would be equal to 30.

Step-by-step explanation:
hello :
(4a) × (3b) =12ab
Answer:
y = 3x - 5
Step-by-step explanation:
The equation of a line parallel to y=3x+6 has exactly the same form but a different constant on the right: y=3x+C
To find C, take the coordinates of the given point and substitute them into y=3x+C:
7 = 3(4) + C, or
7 = 12 + C, and so C = -5
The desired equation is y = 3x - 5
Step-by-step explanation:
my personal opinion is that the answer is 20
