Y=(x-4)/2x-11x+28
y=(x/2x)-(4/2x)-11x+28
y=0.5x-2x-11x-28
1. subtract like terms
2. add 28 on both sides
3. so on and so forth...
To answer this problem, you should know the formula that we will be using and this would be:
Angle of elevation = arc tan( (vertical height)/(length of the shadow)).
Plugging in the values in the formula. Here, this angle is:
arc tan (12.5/18) = <span>34.78 degrees</span>
The answer would be approximately 34.78 degrees
Ok
it might be easier to conver from yards to inches then flip it
1cubic yard=1yard times 1yard times 1yard
1yard=36 inches
1 cubic yard=36 inches times 36 inches times 36 inches
1 cubic yard=46656 cubic inches
divide both sides by 46656
1 cubic inch=1/46656 cubic yards
Answer: a=70°
b=45°
c=65°
d=45°
e=70°
f=110°
Step-by-step explanation:
a=70°
b=180°-135°=45°
c=180-(70+45)=180-115=65°
c=65°
e=70°
d=180-(c+e)=180-(65+70)=180-135=45°
d=45°
f=180-e=180-70=110°
Answer:

Step-by-step explanation:
Since ∆ABD is similar to ∆CBE, therefore, the ratio of their corresponding side lengths would be equal to each other. Thus:

BD = 12 cm
BE = x
AD = 27 cm
CE = 23.4 cm
Plug in the values

Cross multiply


Divide both sides by 27
