You can use tangent trigonometric ratio since that deals with perpendicular and base and since the case is related physically to right triangle, thus it would be useful here.
The height of the considered pole is given by Option B:
<h2>Given that:</h2>
- The person is standing 36 feet away from base of a pole.
- The angle of elevation from base of person to top of pole is 30 degrees.
<h3>To find:</h3>
Height of pole.
<h2>Using tangent ratio to find height of pole:</h2>
Let the height of the pole be x.
In the given figure attached below, we can see that there is a right angled triangle ABC forming.
By using the tangent ratio from angle C, we have:
Thus, the height of the considered pole is given by Option B:

Answer:
1. Not rhombus
2. Rhombus
3. Rhombus
Step-by-step explanation:
The little lines you see represent the size. So if you see one line on all sides, its a rhombus. If you see 1 line on one side, 2 lines on two sides, and 3 on the last side, it is not a rhombus.
Look for the lines.
Answer:
15x² - 3y + 9
Step-by-step explanation:
(12x² + 6y - 3) + (3x² - 9y + 12)
12x² + 6y - 3 + 3x² - 9y + 12
12x² + 3x² + 6y - 9y + 12 - 3
15x² + 6y - 9y + 12 - 3
15x² - 3y + 12 - 3
15x² - 3y + 9
Answer:r=5.78 %
Step-by-step explanation:
Given
time t=12 years
Investment doubles in 12 years when compounded monthly with r rate of interest
where A=amount
P=principal
r=rate of interest
n=no of times interest is compounded per unit time t
t=times
here A=2P
thus
r=0.05789
r=5.789 %
