Answer:
There are three triangle similarity theorems that specify under which conditions triangles are similar: If two of the angles are the same, the third angle is the same and the triangles are similar. ... If two sides are in the same proportions and the included angle is the same, the triangles are similar.

Answer:
55
Step-by-step explanation:
35+90=125
180-125=55
The interior angles of a triangle should always add up to 180 degrees
Step-by-step explanation:
Simplify the following expression then state the property used:
9^-2
Property:
Given,
9^-2
For any real numbers a and b a, b ≠ 0, and for any two positive integers, n and n
a^-m
=> 1/a^m [By doing reciprocal]
So,
9^-2
=> 1/9^2
=> 1/(3^2)^2
=> 1/(3^4)
=> 1/(3*3*3*3)
=> 1/81. Ans.
Hope this helps.
When dealing with radicals and exponents, one must realize that fractional exponents deals directly with radicals. In that sense, sqrt(x) = x^1/2
Now, how to go about doing this:
In a fractional exponent, the numerator represents the actual exponent of the number. So, for x^2/3, the x is being squared.
For the denominator, that deals with the radical. The index, to be exact. The index describes what KIND of radical (or root) is being taken: square, cube, fourth, fifth, and so on. So, for our example x^2/3, x is squared, and that quantity is under a cube root (or a radical with a 3). Here are some more examples to help you understand a bit more:
x^6/5 = Fifth root of x^6
x^3/1 = x^3
^^^Exponential fractions still follow the same rules of simplifying, so...
x^2/4 = x^1/2 = sqrt(x)
Hope this helps!
