MATH HELP PLEASE! ( please show all work)

Answers

Answer:

Step-by-step explanation:

Sin(42) = n/21

n = 21 * sin(42)

n = 21 *  0.6691

n = 14.052

Cos(42) = m / 21

21 * cos(42) = m

m = 21 * 0.7431

m = 15,61

Theta + 42 = 90

Theta = 90 - 42

Theta = 48

A hotel elevator can hold up to 2000 pounds. When 6 people get on it,
they have a combined weight of 1050 pounds. How much additional
weight can the elevator handle?

Help me pleaseeee!!!!

Answers

Answer:

The elavator can handle 950 more pounds.

Step-by-step explanation:

Since the elevator can handle 2,000 lb, and there is currently 1,050 lb on it, you have to subtract the weight that the elevator can handle from the weight that's already on it. So in other words, do 2000 - 1050.
