Hi there!
We know that RST is an equilateral(all 3 sides the same length) triangle, and is therefore equiangular(all 3 angles the same value). Therefore, angle S and is equal to one-third of the triangle's angle measure.
180/3=60
60=7x+4
56=7x
x=8

Answer: 9.
Step-by-step explanation:
8 5/6 is a mixed number with a whole number and a fraction. We want to round to the nearest whole number without the fraction.
First, we convert the mixed fraction to an improper fraction or fraction like this:
((8 x 6)+5)/6 = 53/6
Then, we divide the numerator by the denominator from the previous step:
53/6 = 8.83
Now we have one decimal number. Round using the following rules:
If the number to the right of the decimal point is .5 or higher, then add 1 to the left of the decimal point.
If the number to the right of the decimal point is less than .5, then leave the number to the left of the decimal point as is.
.83 is .5 or higher. Thus, we add 1 to the left of the decimal point. 8 5/6 rounded to the nearest whole number is therefore the answer will be 9.
In this case we are dealing with the pythagorean theorm involving right angled triangles. This theorm states that a^2 + b^2 = c^2 which means the square of the hypotenuse (side c, opposite the right angle) is equal to the square of the remaining two sides.
In this case we will say that a = 3963 miles which is the radius of the earth. c is equal to the radius of the earth plus the additional altitude of the space station which is 250 miles; therefore, c = 4213 miles. We must now solve for the value b which is equal to how far an astronaut can see to the horizon.
(3963)^2 + b^2 = (4213)^2
b^2 = 2,044,000
b = 1430 miles.
The astronaut can see 1430 miles to the horizon.
(22.5+38.25)(4/5)=48.6 or 48 6/10=48 3/5 quarts
