Supplementary angles add up to 180 degrees
Complementary angles add up to 90 degrees
So if angle 2 is x
Then angle 1 is x - 28
And we can set up the equation
x + (x-28) = 180
2x - 28 = 180
2x = 208
x = 104
And then the second equation is:
Angle 1 + Angle 3 = 90
Angle 1 = 104 - 28 = 76
76 + Angle 3 = 90
Angle 3 = 14
So the angles are, again:
∠1 = 76
∠2 = 104
∠3 = 14

The function r =f(t) is f(t) = 1 - 8t/3
<h3>How to evaluate the function?</h3>
The function is given as:
3r + 8t = 3
Make r the subject
3r = 3 - 8t
Divide by 3
r = 1 - 8t/3
This means that:
f(t) = 1 - 8t/3
To calculate f(-3), we have:
f(3) = 1 - 8 * 3/3
Evaluate
f(3) = -7
Also, we have:
1 - 8t/3 = 2
Add 2 to both sides
-8t/3 = 3
Solve for t
t = -9/8
