Answer:
...
Step-by-step explanation:
7x - 2 +5x - 10 +4x = 180
16x - 12 = 180
16x = 168
x = 10.5
now plug it in
7(10.5) - 2 = 71.5°
4(10.5) = 42°
5(10.5) -10 = 42.5°
3/4 x 3/3 = 9/12
9/12 of the ice cream has been eaten

Answer:
$500
Step-by-step explanation:
let x = price of the dress before reductions
If the price is reduced by 60%, the price would be (100% - 60%) = 40%
Price after first reduction= 0.4x
Price after second reduction = 0.4(0.4x)
0.16x = $80
Divide both sides by 0.16
x = $500
Cos(angle) = adjacent/hypotenuse
cos(14) = 20/x
x*cos(14) = 20
x = 20/cos(14)
x = 20.612 <-- value is approximate; make sure to be in degree mode
x = 20.6
Answer: 20.6 feet
