kow [346]

Answer:

\cos(J) = 0.67

Step-by-step explanation:

Given

\angle K = 90^o

KJ = 65

IK = 72

JI = 97

Required

\cos(J)

The question is illustrated with the attached image.

From the image, we have:

\cos(J) = \frac{KJ}{JI}

This gives:

\cos(J) = \frac{65}{97}

\cos(J) = 0.67010309278

\cos(J) = 0.67 --- approximated

a stack of boards is 24 inches high. Each board is 3/8 of an inch thick. How many boards are in the stack?
meriva
To answer this we need to divide 24 by 3/8.

First we need to convert 24 to a fraction. 

\frac{24}{1}

When dividing fraction, multiply the first fraction by the reciprocal of the second fraction. (A reciprocal is an upside down fraction)

\frac{24}{1} * \frac{8}{3} =  \frac{192}{3} (simplify:) 64

The answer is 64
