Answer:
56
Step-by-step explanation:
A straight line is 190 degrees so 190-134=56 hope this helps
You move the decimal point forward until it reaches the one so it looks like this:
1.4 x 10⁵
the exponent, 5, just tells you how many spaces the decimal point moved.
Answer:
1:4
Step-by-step explanation:
A ratio can be written like this: 15:60, but it can also be written as the fraction 15/60, which can be simplified to 1/4, or 1:4.
Answer:
See below.
Step-by-step explanation:
The converse of the Pythagorean Theorem tells us that if the sum of the square of the two shorter lengths is equivalent to the square of the longest length, then the triangle is indeed a right triangle.
We have the side lengths (x²-1), (2x), and (x²+1).
We can see that our hypotenuse will be (x²+1), since it will always yield the largest value for x.
So, we can use the Pythagorean Theorem:

Substitute (x²-1) and (2x) for a and b, and substitute (x²+1) for c:

Square each expression:

Combine like terms:

Add:

We can see that the resulting equations are equivalent, proving that the triangle is indeed a right triangle.
And we're done!
