ATQ

97 + x = 180

x = 180 - 97 (Angles on same line adds upto 180°) (Linear pair cuz 2 angles)

x = 83

The unknown angle is 83°

Hey, guys help me answer!
Sliva [168]

Hello and Good Morning/Afternoon

<u>Let's take this problem step by step.</u>

        5=\frac{1}{3}(5x-15)\\ 5=\frac{5}{3}x-5\\ 5+5= \frac{5}{3}x-5 +5\\10=\frac{5}{3}x\\ 10 * 3 = 3* \frac{5}{3}x\\30=5x\\\frac{30}{5} =\frac{5}{5}x\\ 6=x\\x=6

<u>What did we do in this problem</u>

  • we ensured that both sides remained equally balanced in value
  • took everything step-by-step to make sure that there were no mistakes
  • to check it, we can plug it back into the original equation to see if it works

                  5=\frac{1}{3}(5(6)-15)\\ 5=\frac{1}{3} (30-15)\\5=\frac{1}{3}*15\\ 5=5 \checkmark\\

<u>Answer: x = 6</u>

Hope that helps!

What is the length of BC⎯⎯⎯⎯⎯ ?<br><br><br> Enter your answer in the box.
Rudiy27

Answer:

  \overline{\text{BC}}=\boxed{22}

Step-by-step explanation:

The angle marks mean those angles have the same measure. That means the sides opposite them have the same measure, so ...

  2x -24 = x -2

  x = 22 . . . . . . . . . add 24-x

The length of BC is x, so is 22.

BC = 22
