D.
Take each term and find the degree of the term and then put them in order from highest to lowest:
x=1
Remember a letter without an exponent is assumed to be a 1.
Hope that helps.
The value of x = 108, since the two angles are corresponding, which means they have the same angle, making the angle underneath 108 - 36, which =equals 72, and 72 + 108 = 180
I hope this is help full to you
If daniels age is x years we can create the equation:_
3x = x + 4
2x = 4
x = 2
so Daniel is 2 years old
You can make the equilateral triangle into a right triangle by cutting it in half. So, your sides would be 4.5, 9, and x.
Using Pythagorean Theorem, you know that a^2 + b^2 = c^2.
The 'a' would be equal to 9, and 9^2 is equal to 81.
B is equal to 4.5, and 4.5^2 is 20.25.
So, you have the following:
81 + 20.25 = c^2
And that makes 'c' equal to 101.25.
The square root of 101.25 is approximately equal to 10.06.
So now you know the height, 10.06.
