A right angle= 90
90 x 5/3 = 150
Answer:
n = 6 +
or n = 6 - 
Step-by-step explanation:
We can solve this equation using the quadratic formula OR Completing the Square method.
n² + 14 = 12n
rearrange : n² - 12n + 14 = 0
here a= 1 , b = -12, c = 14
the quadratic formula says: x = - b/ (2a) + root(b^2 - 4ac) / (2a)
or x = - b/ (2a) - root(b^2 - 4ac) / (2a)
x = - (-12)/ (2) + root((-12)^2 - 4*14) / (2)
x = 6 + root (144 - 56) / 2
x = 6 + root(88)/2
x = 6 + root(4*22) / 2
x = 6 + 2*root(22)/2
x = 6 + root(22) = 6 + 
so x =6 +
or x = 6 - 
In this case x = n
n = 6 +
or n = 6 - 
Answer: I chose question number 1.
2 coconuts= 2 points
1 coconut + 1 apple (10 points) + Banana (4 points)= 15 points.
Answer:
66
Step-by-step explanation:
angle 1 and 4 are supplementary so the 2 added together equal 180. 180-124=56.
The sum of the triangles angles equal 180
180-56-58=66 which is the value of angle 2
There are no constants here. But we have x and y here.
We will create an equation which is:
2y+3x=54.
But we will also create a second equation which states the number of seats.
x+y=24.
Now we do the two-equation solving method.
2y+3x=54
-2(x+y=24)
2y+3x=54
-2x-2y=-48
x=6
To solve for y, plug in x into one of the original equations. Which one doesn't matter.
y+6=24
y=18
