Answer:
about 28
Step-by-step explanation:
you have to use the sine rule = side you know * ( sin of angle opposing the side you want to know / sin of angle opposing the side you know)
AB = 19* (sin 75/ sin ( 180 -75-64) )
AB = 19 * ( sin 75 / sin 41) ≈ 27.9739...
Answer:
It is proportional
Step-by-step explanation:

Answer:
yes, he would have enough money
He would need a total of 1.5 gallons to paint the wall .
the cost of 1.5 gallons is $18 dollars.
Andrew has 40. he has enough money
Step-by-step explanation:
total gallon needed to pain four walls = 3/8 x 4 = 1 1/2 gallons
total cost of 1 1/2 gallons = 1 1/2 x $12
to calculate this amount convert 1 1/2 to improper fraction
to convert to improper fraction, take the following steps :
1. Multiply the whole number by the denominator
2. Add the numerator to the answer gotten in the previous step
3. divide the number gotten in the previous step by the denominator
3/2 x $12 = $18
Let s be the son's age 15 yeasr ago and m the mother's age that year.

We also know that:

Plotting vallues:

Remember that they were that age 15 years ago.
So their actual age is 30 and 60.
