A= 15

Step-by-step explanation:

First step is we make an equation. As we know, the line is known as a straight angle, which always equals 180°. To make the equation, we are going to plug in the information we had, 4a° and 120°, plus our new information which is 180°. The equation should look like this.

4a°+120°=180°

We then subtract 120 from each side which will simply it to

4a°=60

We then have the leave the variable, a, by itself. To do that we must divide 4 to each side which will leave us with our answer.

a°=15

To verify our answer we can plug 15 back to the equation.

4(15)°+120°=180° = 60°+120°=180° = 180°=180°

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
