Answer:
C
Step-by-step explanation:
The line passes through the point (2, -1/2) and has a slope of 3.
We can use the point-slope form, given by:
Where (x₁, y₁) is a point, and m is the slope.
Let (2, -1/2) be (x₁, y₁). We will substitute 3 for m. Therefore:
Simplify:
Therefore, our answer is C.
Answer:
Height of flagpole = 571 ft
Step-by-step explanation:
Given:
Angle of elevation to the top of the flagpole is 55° .
Distance from the eyes to the base of flagpole = 400 ft.
To find the height of the flagpole.
Solution:
We can draw the situation as a right triangle as shown below.
In triangle ABC.
∠C= 55°
To find the length AB (height of the flagpole).
Applying trigonometric ratio :
Plugging in values.
Multiplying both sides by 400.
∴
Height of flagpole = 571 ft
