Answer:
B
Step-by-step explanation:
To find the area, multiply length by width (lw, or l×w). If the length is 10, that just leaves the width, which is unknown. We can substitute 10 for l, which leaves us with 10w.
Substitute the x with 5
-(5)2 + 4(5) - 10 = 0
Cos = adjacent over hypotenuse
cos33 = b/170
170cos33 = b
b = 142.574 inches
84/12 is 7 so it’s 7 feet and to find out how many inches, you have to subtract 84-75 which is 9 that that’s 9 inches
7 feet and 9 inches
