Circle touches all tree sides of the triangle, so the circle is inscribed.
True.
A right triangle follows the Pythagorean theorem: a^2 + b^2 = c^2
Let’s work out the problems
1. 20^2 + 72^2 = 75^2
40 + 5184 = 5625
False
2. 40^2 + 74^2 = 85^2
1600 + 5476 = 7225
False
3. 45^2 + 60^2 = 75^2
2025 + 3600 = 5625
True
The correct answer is (45, 60, 75)

Answer:</h3>
5
<h3>
Step-by-step explanation:</h3>
Let n represent the numerator of the original fraction, which is n/(n+4). After adding 1/2, the value is (2(n+4)+1)/(2(n+4)), so we have ...
n/(n+4) + 1/2 = (2(n+4)+1)/(2(n+4))
Simplifying gives ...
... (2n +(n+4))/(2(n+4)) = (2n +9)/(2(n+4))
Since the denominators are the same, we can work only with the numerators.
3n +4 = 2n +9
n = 5 . . . . . . . . . . . subtract 2n+4

<em>Check</em>
The original fraction is 5/(5+4) = 5/9. Adding 1/2 gives ...
5/9 + 1/2 = 10/18 + 9/18 = 19/18
Note the numerator of this last fraction is 1 more than the denominator, which is twice the original denominator.
Answer:
C. Both statements are true
Number 3) 56 because 5|...6= 56
Number 4) is B because Graph 2 distorts the data by not starting the axis at zero whereas Graph 1 does start the axis interval at zero
