<span>It is important to know that the sum of the three angles inside a triangle add up to 180 degrees. So then we get the following by adding up all three provided angle measures:
3x + (2x + 20) + (4x - 20) = 180
Some algebraic manipulation follows:
3x + 2x + 20 + 4x - 20 = 180
9x = 180
x = 180/9 = 20
The value of x is 20 degrees.</span>
Answer:
8.) Rational
10.) Irrational
Step-by-step explanation:
8.) This is rational because although it is a decimal, it is terminating, meaning it has an end.
10.) This is irrational because it is a repeating decimal with seemingly no pattern.
600 miles.....25 miles per gallon...
600/25 = 24 gallons are used
1 gallon = 3.78541 liters....then 24 gallons = (24 * 3.78541) = 90.84984 liters
at 1.12 per liter = (1.12 * 90.84984) = 101.75 <=
