Answer:
Step-by-step explanation:
The easiest way to do this is to use the distributive property.
Put the brackets around the terms on the right.
b = (f^2 * A + 2HA)
A is a common factor on the right.
b = A * (f^2 + 2H)
Now divide by f^2 + 2H
b/(f^2 + 2H) = A

Answer: 8/17
Step-by-step explanation: The ratio for tangent is opposite/adjacent. The side opposite from Y has a length of 8, and the side next to it has a length of 15. These are the lengths of the legs of the triangle. To find the sine ratio, you need the hypotenuse.
The hypotenuse can be found using the Pythagorean theorem. 8^2=64 and 15^2=225. 225+64=289. The square root of 289 is 17. The hypotenuse has a length of 17.
The ratio for sine is opposite/hypotenuse. Take the value of the opposite from the tangent ratio (8) and the length of the hypotenuse (17) to get 8/17.
Answer:
x = 14
Step-by-step explanation:
Since the triangles are similar then corresponding sides are in proportion, that is
= 
( cross- multiply )
12(x - 4) = 120 ( divide both sides by 12 )
x - 4 = 10 ( add 4 to both sides )
x = 14
Answer:
A,B
Step-by-step explanation:
It could be A or B because them stepping on a rock could cause the rock to crack and another could come along and do the same thing and the rock would eventually break.
