Hello :
a = w l
l = a/w
l =( 6x²y+4y²x)/(2xy)
l = 2xy(3x+2y) /(2xy)
l = 3x+2y
Answer:
(2, 18) or x = 2 and y = 18
Step-by-step explanation:
From substitution:
9x = 3x + 12
6x = 12
x = 2
y = 9x = 9 * 2 = 18
Answer:
As the property of angle in a circle:
angle BAC = arc BC = 116 deg
=> angle BHC = (1/2) angle BAC =(1/2) x 116 = 58 deg
angle HCG = (1/2) arc HF = (1/2) x 24 = 12 deg
B, H , G are on the same line, then:
angle BHC + angle CHG = 180 deg
=> angle CHG = 180 - angle BHC = 180 - 58 = 122 deg
Consider sum of three angles in triangle CHG, then:
angle CHG + angle HCG +angle HGC = 180 deg
=> angle HGC = 180 - angle CHG - angle HCG = 180 - 122 - 12 = 46 deg
=> angle BGC = angle HGC = 46 deg
Hope this helps!

Answer:
<em>Corey stepped back 59.71 feet</em>
Step-by-step explanation:
<u>Right Triangles
</u>
They are a special type of triangle where one of its internal angles is 90°. The basic trigonometric equations stand in this type of triangles. If x is the adjacent leg of a given angle 
, and y is the opposite leg to the same angle, then
:
We can solve for x to get
Corey estimates the height of the tree to be 80 feet. This means we know y=80 and 
. Let's find the horizontal distance at which Corey is looking at the bald eagle:
Now Corey moves back to watch the very same tree at an elevation angle of 41°. The tree has the same height, so
Now we can know the distance Corey walked back by subtracting both distances
