Using the pythagorean theorem: c^2 = a^2 + b^2
c = 12 feet
a = 3 feet
b = x feet
12^2 = 3^2 + x^2
144 = 9 + x^2
144 - 9 = x^2
135 = x^2
x = 11.6 feet
Therefore, the answer is B.
Answer:
Tangent = opposite / adjacent
Tangent of 45º equals 1
Step-by-step explanation:
X= a number
29 - 2x= 21
subtract 29 from both sides
-2x= -8
divide both sides by -2
x= 4
CHECK:
29 - 2x= 21
29 - 2(4)= 21
29 - 8= 21
21= 21
ANSWER: The number is 4.
Hope this helps! :)
Answer:
106
Step-by-step explanation:
The pattern is +8. 66 is the last number given which is the 5th number. So we need to have five numbers. we can do 8*5=40 and add 40 to 66. Your answer is 106.
When you divide two powers of the same base, you subtract the exponents:
This means that, in your case,
So, if 
, the equation becomes
