Step-by-step explanation:
(-7)+(-6)+(-1)=-14
(-14)-3=-11
-11÷7=-1.5714285714286 or -2 if you round too the tenths place
10 dollars because half of 10 is 5 and when you add 8 you get 13
Okay
now draw a right angled triangle
labeling the hypotenus 57ft
the opposite x and the adjacent 5.5 ft and the angle in the right angle triangle is 55 °.
now solve
sin 55°=x/5.5
0.8192(the sin of 55)= x/5.5
cross multiply
X=4.51
