Answer:
Lawns ---Earnings
1 ----------------- 10
2 ----------------- 20
3 ----------------- 30
5 ----------------- 50
Step-by-step explanation:
Given
Earnings = $10 per lawn
Required
Complete the table
Let y be the earnings for x number of lawns
Since he earns $10 per x lawns, then the expression is:

To complete the table, we have the following:
When x = 1

When x = 2

When x = 3

When x = 5

So, the complete table is:
Lawns ---Earnings
1 ----------------- 10
2 ----------------- 20
3 ----------------- 30
5 ----------------- 50
Answer:
20°
Step-by-step explanation:
The sum of angles in a ∆ = 180°
Therefore,
Use this expression to find the value of x, then find the measure of angle A.

Subtract 20 from both sides


Divide both sides by 20


Find measure of angle A.
Angle A is given as 
Plug in the value of x and solve

Sine (34) = opposite / 99
opposite side = .55919 * 99
