Answer:
A triangle with three angles that each measure between 0º and 90º.
A triangle with one angle that measures between 90º and 180º.
A triangle containing a right angle.
Answer:
2, quadratic, 1
Step-by-step explanation:
Degree is the highest power which is 2 then the lead coefficient is the constant multiplying the highest power so for x^2 it is 1 and the type of equation is what is it, linear, quadratic, cubic, etc. For this it is quadratic because x^2 means its a parabola.
Answer: the distance of the boat from the foot of the lighthouse is 290.5 feet.
Step-by-step explanation:
The right angle triangle ABC representing the scenario is shown in the attached photo.
Angle A is alternate to the angle of depression, hence, they are the same.
The height of the lighthouse represents the opposite side of the right angle triangle. The distance, x of the boat from the foot of the lighthouse represents the adjacent side of the right angle triangle.
To determine x, we would apply
the tangent trigonometric ratio.
Tan θ, = opposite side/adjacent side. Therefore,
Tan 11.1 = 57/x
x = 57/Tan 11.1 = 57/0.1962
x = 290.5 feet to the nearest tenth.
The surface area formula is 4 x pi x r^2
Answer:
I believe the answer is six-hundred thousand (600000). That's if I read your question right. I'm not sure what you were asking exactly.
Step-by-step explanation:
6 (10000 x 10)
6 (100000)
600000
