Solve for C when 9=c(c-8)<br><br> Can you show your work too? This question confuses me!
Marrrta [24]
9 = c(c - 8)
9 = c² - 8c
c² - 8c - 9 = 0
c² + c - 9c - 9 = 0
c(c + 1) -9 (c + 1) = 0
(c+1)(c-9) = 0
c = -1 or 9

In short, Your Answers would be -1 and 9

Hope this helps!

If angle 1 and angle 2 are supplementary angles, and angle 3 and angle 2 are supplementary angles, what do you know about angle
dusya [7]

Answer:

  angle 1 and angle 3 are congruent

Step-by-step explanation:

Angles supplementary to the same angle are congruent. Here both angles 1 and 3 are supplementary to angle 2, so angles 1 and 3 are congruent.

_____

If you like, you can get there algebraically:

  m∠1 + m∠2 = 180

  m∠3 + m∠2 = 180

Subtract the second equation from the first:

  (m∠1 + m∠2) - (m∠3 + m∠2) = (180) - (180)

  m∠1 -m∠3 = 0 . . . . simplify

  m∠1 = m∠3 . . . . . . add m∠3

When angle measures are the same, the angles are congruent.

  ∠1 ≅ ∠3
