Which equation can be used to find the measure of angle lkj? cos−1(startfraction 8.9 over 10.9 endfraction) = x cos−1(startfraction 10.9 over 8.9 endfraction) = x sin−1(startfraction 10.9 over 8.9 endfraction) = x sin−1(startfraction 8.9 over 10.9 endfraction) = x

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

In the right triangle LKJ of the figure

The sine of angle LKJ (x) is equal to divide the opposite side to angle LKJ (LJ) by the hypotenuse of the right triangle (KJ)

so

substitute the given values

therefore

step-by-step explanation:

milk=16 large

soda=280 kids

juice box=82 regular

63 soda +63 regular

124 large total

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
