Angle CFE should be 87°

I don't know how to do the last problem, sorry.

You are trying to find the angle at point F. Line AB and DF are parallel.

∠B is the same as∠C, so ∠C = 120°

A straight line is 180°. To find the other angle of the triangle, you do this:

120 + ? = 180

? = 60°

Now that you know 2 of the 3 angles, you can find angle F.

60 + 33 + ∠F = 180

∠F = 87°

Emilio asked his aunt for $20 to buy supplies for his lemonade stand. Once his stand opened he made $40 a day
FrozenT [24]

The equation that represents profit is $40x - $20.

The profit after 5 days in business is $180.

The profit after 10 days in business is $380.

The profit after 10 days in business if revenue is $45 is $430.

<h3>What is profit? </h3>

Profit is total revenue less total cost.

Profit = total revenue - total cost

Profit = $40x - $20

Where:

x = number of days

<h3>What is the total profit after 5 days and 10 days? </h3>

$40(5) - $20

= $200 - $20

= $180

$40(10) - $20

$400 - $20

$380

<h3>What is total profit if revenue is $45? </h3>

$45(10) - $20

= $450 - $20

= $430
