So you take 20 inches and times it by 4 which equals 80 inches. So then you would take to 80 inches and divide by 108. then you will get your answer.
MCE = 360 - (150 + 70 + 50)
mCE = 360 - 270
mCE = 90
<CDE = 1/2(mBE + mCE)
<CDE = 1/2(150 + 90)
<CDE = 1/2(240)
<CDE = 120
answer
<CDE = 120°
What is the question? I don't understand please explain?
Expressions are problems with no answer. I would use it to represent inequalities and/or a basic formula
