Answer:
I believe its 16.
Step-by-step explanation:
Because 2 x 2 (for the square) is 4. 2 x 3 is 6, and 6 divided by 2 is 3. And 3 x 4 (for all the triangles) is 12. So 12 + 4 is 16. So the surface area should be 16.
Answer:
The answer is C (No. These are dependent events and you can calculate the probability of this outcome using the formula)
X^2 + 6x +9
(x+3) (x+3)
x+3 = 0
x = -3
answer: x=-3
Answer:
11.3°
Step-by-step explanation:
Refer the attached figure .
Height of building i.e. AB = 160 feet.
A helicopter takes off from the ground 800 feet from the base of a building i.e. BC = 800 ft.
We are required to find what angle did the helicopter take off from i.e. ∠ACB
We will use trigonometric ratio .







Thus the angle at which the helicopter take off from is 11.3°
