43. A beam rests against a wall, forming a 65º with the floor. Use the function y = 9 sec 8 to find the
length of the beam to the nearest tenth of a foot.

Step-by-step explanation:

Look the picture I attached you. As you can see the beam against the wall form a right triangle. The trigonometry functions on a right triangle are:

The problem give us the following data:

Using the previous information about the trigonometry functions on a right triangle and the data provided by the problem you can conclude:

Therefore:

step-by-step explanation:

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
