Answer:8sqrt 2 or sqrt 128
Step-by-step explanation:
We can use the Pythagorean Theorem. Since the ladder is leaning against the wall, it is the hypotenuse. It is also 4 feet away from the wall so 12^2-4^2=b^2 b^2=128 so b=8sqrt 2 or sqrt 128.
The answer is:
6 = 9x + 27
depending on what you are supposed to do.
Answer:
x = 35
Step-by-step explanation:
Since m1=m2 :

Answer:
is not equal to 
Step-by-step explanation:
When a power of 10 is positive the dot must be moved to the right, and when the power of 10 is negative, the dot must be moved to the left.
For example
and 
So

wich is clearly not equal to 0.000002015
the correct scientific notation for 0.000002015 must be:
With a negative in the power of 10, referring to a small quantity.
Answer:42.98
Step-by-step explanation:
Hf=√(11^2-8^2)
Hf=√(121-64)
Hf=√(57)
Hf=7.5
11/sin90 =7.5/sinG
Sin90=1
11/1=7.5/sinG
Cross multiply
11 x sinG=7.5 x 1
11sinG=7.5
Divide both sides by 11
11sinG/11=7.5/11
sinG=0.6818
G=sin(inverse)(0.6818)
G=42.98
