This is all about right triangles, assuming the tower is not the leaning tower of pisa! The tower is our height of the right triangle, the base of our triangle is the distance Nadia is from the tower, and the reference angle is 30 (the base angle that is NOT the right angle). The tower is opposite this reference angle, and the side 60 is adjacent to this angle, so we will use the tangent ratio, the trig identity that relates the side opposite the reference angle to the side adjacent to it.
. Solving for x we get x = 60 tan(30°). On our calculators that gives us that x = 34.64. That's how tall the tower is.
Answer:
You can't. It is a false statement. There is nothing to solve.
Step-by-step explanation:
The "equation" resolves to ...
-72 = -35 . . . . a false statement with nothing to solve for
Answer:
x=-10/3
Step-by-step explanation:
(2x+4)=-4(-2x-6)
distribute -4 to (-2x-6) by multiplying
negative multiplied by a negative is a positive
8x+24=2x+4
subtract 24 from each side
8x=2x-20
subtract 2x from each side 6x=-20
divide both sides by 6
-20/6
simply to -10/3 or -3 1/3 or -3.3
x=-10/3

Answer:
-6x + 22
Step-by-step explanation:
Note: This problem doesn't have a sign between 2 and 16, we would have to assume it is addition since 16 is 16 positive.
First we have to do distributive property,
-4 x 3x = -12x and -4 x -1 = 4
The equation should look like this:
-12x+4 + 6x + 2 + 16
Then combine like terms meaning do -12x + 6x
The answer should be -6x
The equation: -6x + 4 + 2 + 16
Then solve 4+2+16 which should equal 22
The answer: -6x + 22
Simplified!
