Answer:

Step-by-step explanation:
we know that
To find the fraction of the store's books that are fiction mysteries, multiply 1/2 by 3/5
so

Answer:
these triangles some is 90°.
72°+2x=90°
2x=90°-72
2x=18
x=18/2
x=9
Step-by-step explanation:

Answer:
c > 5
Step-by-step explanation:
The properties of equality can be used to solve inequalities. Attention needs to be paid to ordering.
<h3>Application</h3>
We can subtract 3 from both sides to solve this.
c +3 > 8 . . . . . . given
c +3 -3 > 8 -3 . . . . subtract 3 from both sides
c > 5 . . . . . . . . . simplify
The solution is c > 5.

<em>Additional comment</em>
Adding or subtracting a value to a number on a number line is equivalent to shifting it right or left. It does not change ordering.
Multiplying or dividing by a <em>positive</em> number is equivalent to expanding or compressing the distance from zero. It does not change ordering.
Multiplying or dividing by a <em>negative</em> number reflects the value across the origin, in addition to expanding or compressing the distance from zero. This reflection reverses the left-right ordering. For example, -2 < -1, but 2 > 1. (Both numbers multiplied by -1.)
As long as you're aware of the effect on ordering, you can use any of the properties of equality to solve inequalities.
This is a simple

Pythagorean Theorem problem.
So here we go:
Imagine a right triangle with 2 legs and a hypotenuse.
The Pole is the vertical leg. The Cable is the hypotenuse. The distance on the ground between the cable and the pole is the 3rd leg.
We are trying to find the hypotenuse which is C in our Pythagorean Theorem.
Thus:

Add the squares:

Now take the square root of both sides:
*Remember that in triangles, we cannot have a negative value for the length. (If it's possible, please contact the Nobel Prize admins).

Thus:
