Answer:
12.3 feet of chain is your answer.
Answer:
x = 27°
Step-by-step explanation:
m<D
m<CBE = 63° (Given)
m<CBE = m<ABD (vertical angles)
m<ABD = 63° (substitution)
x = 180 - (m<ABD + m<D) (Sum of triangle)
x = 180 - (90 + 63)
x = 27°
Where is the rest of the question?
He sold 18 tickets class play tickets. Hope this helps :)
Complementary angels add up to 90°
so x+18°=90°
so x=90-18=72°
