Answer:
<h2>
30° and 150° </h2>
Step-by-step explanation:
α - one angle
2α - two times measure of angle α
2α + 30° - second angle
Paralleogram has two pairs of angles of the same measure.
Sum of interior angles of any quadrangle is 360°
Therefore:
2×α + 2×(2α + 30°) = 360° {divide both sides by 2}
α + 2α + 30° = 180° {subtract 30° from both sides}
3α = 150° {divide both sides by 3)
α = 50°
2α+30° = 2×50° + 30° = 130°
The answer is $29.3 because you multiply 2.93 times the ten gallons of gas.
The answer is going to be a fraction...which is 75/1000, otherwise known as 1/40
Answer: 54.29%
Step-by-step explanation:
Given: The probability that they will win both games is 38%.
i.e. P( both games will win) =0.38
The probability that they will win just the first game is 70%.
P(first game will win) = 0.70
To find : P(second game will win| first game will win)
Using formula: 
So, P(second game will win| first game will win) = 
Hence, the required probability = 54.29%
Another way to do it is
2x-y=17
x-y=10, x=10+y
substitute x=10+y for x in 2x-y=17 and get
2(10+y)-y=17
20+2y-y=17
20+y=17
subtract 20 from both sides
y=-3
subsitute y=-3 into equation x-y=10
x-(-3)=10
x+3=10
subtract 3 from both sides
x=7
or subsitute into 2x-y=17
2x-(-3)=17
2x+3=17
subtract 3 from both sides
2x=14
divide both sides by two
x=7
