Answer:
c
Step-by-step explanation:
n + q = 35
n = 35-q
0.05n + 0.25q = 8.15
0.05(35-q) +0.25q = 8.15
1.75 -0.05q + 0.25q =8.15
1.75 + 0.20q = 8.15
0.20q = 6.40
q = 6.40 / 0.20 = 32
32 quarters and 3 nickels
Answer:
103.92 m
Step-by-step explanation:
The kite is making right angle with the ground and its string is acting as hypotenuse of right triangle.
Let the height of the kite from the ground be h meters.
Therefore, by trigonometrical ratio:
Thus, the height of the kite from the ground is 103.92 meters.
We use the law of Cosines to be able to find : 1. The measure of the
third side, when the measure of two sides and the included angle of a
triangle ABC are known. 2. The measure of any angle, when the measure of
the three sides of a triangle ABC are known.
The Law of Cosines is c² = a² + b² - 2abcosΘ. It has four variables;
a, b, c and Θ. Whenever you have a triangle with three of these
variables known, use the Law of Cosines to calculate the unknown
variable.
