Answer:

60°

Step-by-step explanation:

Sum of angles of triangle = 180°

x + 40 + 80 = 180

      x + 120 = 180     {Subtract 80 from both sides}

                x = 180 - 120

                x = 60°

What is the percentage change for 60 to 35
Reil [10]
Let x represent the percentage change. The percentage change is a factor that the original number is multiplied to get the new number.

60*x = 35
x = 35/65 = 0.53846 = 53.846%

<h3>Answer:  Around 4681 grills</h3>

============================================

Explanation:

x = number of years

y = number of grills sold

The equation we'll use is the exponential equation y = 3300(1.06)^x

The 3300 of course is the initial amount sold. The 1.06 as the base indicates that the sales increase by 6% each year. Think of it the 1.06 as 1+0.06 = 100% + 6%

If we plugged x = 0 into that equation, then we get

y = 3300(1.06)^x = 3300(1.06)^0 = 3300

which helps confirm the correct equation.

----------------

Now plug in x = 6 to find the sales for year 6.

y = 3300(1.06)^x = 3300(1.06)^6 \approx 4681.11 \approx 4681

The projected sales for year 6 are about 4681 grills. This is an estimate based on the assumption that the sales will increase by 6% each year. Of course, the reality is that things aren't always so simple like this (but it should give a fairly good idea of what's going on).
