How to get a 22 degree angle in a right angle triangle?

1 answer:

4 0

One way would be to draw 2 perpendicular lines whose lengths are in the ration of the tangent of 22 degrees.

tan 22 = 0.4040

So draw a line AB of length 10 inches, then using a compass construct a perpendicular line at point A Then measure a length of 4.04 inches along this line to point C. Then join CB.

The function A = 15x - x2, where x is the width in yards, gives the area A of a llama pen in square yards. Make a table using 1/

Mnenie [13.5K]

Answer:

The width which gives the greatest area is 7.5 yd

Step-by-step explanation:

This is an application of differential calculus. Given the area as a function of the width, we simply need to differentiate the function with respect to x and equate to zero which yields; 15-2x=0 since the slope of the graph is zero at the turning points. Solving for x yields, x=7.5 which indeed maximizes the area of the pen
