Answer:
cos C= 15/39
Step-by-step explanation:
19,3/4 = 79/4
15,3/4 = 63/4
Perimeter = 79/4+79/4+63/4+63/4 = 284/4 = 71feet
22,1/2 = 45/2 X 4 = 90
90-71= 19 feet
Let me know if you need more of an explanation, but the answer in 19 feet (option 4)
<span>2**n. (That's two to the nth power: 2 to the first, 2 to the second (or two squared), 2 to the third (or two cubed), 2 to the fourth, etc.)
2**1 = 2 = 2
2**2 = 2 * 2 = 4
2**3 = 2 * 2 * 2 = 8
2**4 = 2 * 2 * 2 * 2 = 16 </span>
Y = mx + b
4 = 6(1) + b
b = -2
equation
y = 6x -2
