Step-by-step explanation:
If Alice is 10 inches, she is 2/3 as tall as the door. At her regular height, to be 2/3 as tall as the door the door would have to be 75 inches high.
Answer:
y = x-4
Step-by-step explanation:
First find the slope
m = ( y2-y1)/(x2-x1)
= ( -3 -1)/( 1 - 5)
= -4/-4
= 1
Then using slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = 1x+b
Substitute one of the points in
1 = 5 +b
1-5 = b
-4 =b
y = x-4
Answer:
Height of the antenna = 28 ft (Approx)
Given:
Length of base = 300 ft
Angle of elevation to the building = 40°
Angle of elevation to the antenna = 43°
Find:
Height of the antenna
Computation:
Using trigonometry function:
Tan40° = Height of building / Length of base
Height of building = 251.73 ft
Tan43° = [Height of building + Height of the antenna] / Length of base
0.9325 = [251.73 + Height of the antenna] / 300
Height of the antenna = 28.02 ft
Height of the antenna = 28 ft (Approx)
