Answer:
CAB = 30.71 BCA = 90 ABC = 59.29
Step-by-step explanation:
BCA = 90
9x + 6 + 5x = 90
14 x = 90-6 = 84
x = 43/7
(43/7 ) * 5 = 30.71
90 - 30.71 = 59.29
20 5/81 in its simplest form is 20 5/81.
20 5/81 originally looks like this ⇒ 1625/81
((20 * 81)+5)/81 = (1620+5)/81 = 1625/81 * this is an improper fraction because the numerator is greater than the denominator. Improper fractions must be converted to proper fractions. It will then become a mixed fraction.
