Use a protractor to measure the degrees of the angles. Then, join them together.
Answer:
Step-by-step explanation:
Rick and Debbie are painting a large barn. Debbie paints twice as fast as Rick. They work together for 16 hours and complete the job. Determine how fast Debbie and Rick can paint the entire barn separately.
= 1/a + 1/2a = 1/16
= 2a + a/2a² = 1/16
2a/2a² = 1/16
= 1/a = 1/16
The distribution is skewed to the right
ES = ET
and
DS = DR
and
CR = CT ( because each pair are tangents to the circle)
So ES = 31 and Ds = 65-31 = 34
and DR = 34 and CR = 74- 34 = 40.
CT = CR = 40
Therfore the line EC = 31 + 40 = 71
Finally the perimeter = 65 + 74 + 71 = 210 (answer)
