Step-by-step explanation:
Answer:
Step-by-step explanation:
We know two sides and the angle between the sides, so we can use the Law of Cosines. Recall that the Law of Cosines states that:
, where a and b are the sides and C is the angle in between.
Let's substitute 115 for a, 178 for b, and 41 for Angle C.
Thus:
Answer:
meters
Step-by-step explanation:
Recall to find the circumference of a circle the formula is or .
We start by substituting 4.7m for r in the second circumference formula.
. We input this value of r into the area formula.
Check the picture below, so the parabola looks more or less like so, with a vertex at (0 , -7), let's recall the vertex is half-way between the focus point and the directrix.
so this horizontal parabola opens up to the left-hand-side, meaning that the "P" distance is a negative value.
