Answer:
see the explanation
Step-by-step explanation:
we know that
An equilateral triangle has three equal sides and three equal interior angles.
The measure of each interior angle is 60 degree
see the attached figure to better understand the problem
Let
b ----> the length side of the triangle
In the right triangle ABD
----> by SOH (opposite side divided by the hypotenuse)
substitute the given values
solve for b
Remember that
substitute
simplify
the graph of 13y + kx = 4 and the line containing the points (5, -8) and (2, 4) are parallel.
We find the slope of parallel line using two given points
(5, -8) and (2, 4)
Slope formula is
so slope = -4
Slope of any two parallel lines are always equal
Lets find the slope of the equation 13y + kx = 4
Subtract kx on both sides
13 y = -kx + 4
Divide both sides by 13
Now slope = -k/13
We know slope of parallel lines are same
So the slope of 13y + kx = 4 is also -4
Hence we equation the slope and find out k
Multiply by 13 on both sides and divide by -1
k = 52
the value of k = 52
It would be 48in because 4 times 6 is 24 and 24 times 2 is 48
Answer:
The correct answer is "decrease, 1,280 feet".
Step-by-step explanation:
The given values are:
Rate or speed,
= 320 feet per hour
1 pm to 5 pm means,
t = 5 - 1
= 4 hours
Now,
The net change in distance will be:
⇒
⇒
Thus the above is the correct approach.
The answer is 50, and it can be solved using the percent proportion
