Step-by-step explanation:
Remark
AC and BC are the legs of a triangle. You are told that the right angle is at C. Both these sides have one endpoint C. That means that they are the shorter of the three lines. The first thing we must do is find the Hypotenuse. You need the Hypotenuse to get the sin of one or both of the acute angles.
Hypotenuse
a^2 + b^2 = c^2
a = 7
b = 24
c = ?
c^2 = 7^2 + 24^2
c^2 = 49 + 576
c^2 = 625
sqrt(c^2) = sqrt(625)
c = 25
Find the Largest Angle
The largest angle is going to be opposite the longest leg (not the Hypotenuse although you use the hypotenuse).
Sin(A) = 24/ 25
Sin(A) = 0.96
A = Sin-1(0.96)
A = 73.74
x + y = -9
x + 2y = -25
Rewrite the first equation as x = -9-y
Relace x in the second equation:
-9-y + 2y = -25
Simplify:
-9 +y = -25
Add 9 to both sides:
y = -16
Now you know y,, replace y in the first equation and solve for x:
x -16 = -9
Add 16 to both sides:
x = 7
Answer: x = 7

Answer:
It would take 86.4 gallons of gas to go 1,836 miles.
Step-by-step explanation:
the situation can be explained by the equation 16x=340, where x is how many miles the car can go in one gallon. divide both sides by 16 to get that answer
x=340/16= 21.25
Now the other problem can be expressed by the equation 21.25y=1836, where y is the amount of gallons it would take to go 1,836 miles.
divide both sides by 21.25 to get the amount of gallons
y= 1836/ 21.25= 86.4.
