Johnny is 21 years old.
If you take 21 and add 16, you get 37.
21+16= 37
21-16= 5
The line tangent to the curve at
has slope

Then the tangent line has equation



Answer:
x = 23 degrees
Step-by-step explanation:
Supplementary angles add up to 180 degrees. Thus, 3x - 17 degrees plus al 5x + 21 deg must equal 180 degrees.
Combining like terms, we get 8x - 4 = 180, or 8x = 184.
Dividing both sides by 8 yields x = 184/8 = 23 = x (measured in degrees)
