Step-by-step answer:
The first step in solving a problem of geometry and trigonometry is to draw a diagram, with all the given information in it. The attached image does just that.
Here, we have (horizontal) distance of building to the tower is 400'.
We see two right triangles, each with a leg of 400' (horizontal).
The vertical distances are denoted h1 and h2 for the angles of elevation 24 and 20 degrees respectively.
Using the definition of tangent, we have
h1= 400tan24=178.1
h2=400tan20=145.6
The height of the tower is therefore h1+h2=178.1+145.6=323.7 feet
Hm
10 + 4 x 2 - 3
=10 + 8 - 3
=18 - 3
=15
Oh idk and idc cuz i just really don’t so yea
Answer:
16%
Step-by-step explanation:
The data provided on brand purchased by age group is.
A total of 50 cars were sold this month.
Since the number of buyers 40 years or older that purchased a Honda is 8, the percentage is:
16% of buyers were 40 years or older and purchased a Honda.
Let the side length of the square be x, then A = x^2
but diagonal (z) = sqrt(2x^2)
z^2 = 2x^2
x^2 = 1/2 z^2
Thus, A = 1/2 z^2
dA/dz = 1/2 (2z) = z
The rate of change is z.
When z = 4, the rate is 4.
