The answer is 42 degrees.

A triangle has to equal 180 degrees in total. Because you know it is a right triangle and b is the right angle you make angle a plus c equal 90. You add together 8x and 9x to get 17x and add the 2 and 3 to get 5. You have to solve for x so you subtract 5 from both sides to get 17x = 85. To get x alone you divide both sides by 17 giving you x=5. Now that you have x you plug it into to the equation for angle a. This gives you 8(5)+2 which equals 42.

8x+2+9x+3=90
17x+5=90
17x=85
X=5

8(5)+2=
40+2=42

Answer:

18,500 , 1 , 1.03

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.

f(t) =18,500(1.03)^t

1st blank:

19,055

1.03

18,500

2nd blank:

t years

2 years

3 years

1 year

3rd blank:

19,055

18,500

1.03

My answer:

Given that: f(t) =18,500* $1.03^{t}$

1st blank:

Initial value when t = 0, so we have:

f(0) =18,500* $1.03^{0}$

$f(0) =18,500(1)\\ f(0) =18,500$

So we choose D for 1st blank

2nd and 3rd blank:

Because it's an exponential function f(t) =18,500* $1.03^{t}$ , with every value of t increment f(t) increase by a factor of 1.03 . So Every 1 year the number of students who enroll at the university increases by a factor of 1.03

=> 2nd blank: 1

=> 3rd blank: 1.03

Hope it will find you well.
