Answer:
7, 12, 13
Step-by-step explanation:
Use the Pythagorean theorem equation on all of them. The one that does not make the equation true is the answer.
a^2 + b^2 = c^2
A.
a^2 + b^2 = 18^2 + 80^2 = 6724
c^2 = 82^2 = 6724
Right triangle.
B.
a^2 + b^2 = 7^2 + 12^2 = 193
c^2 = 13^2 = 169
Not a right triangle.
C.
a^2 + b^2 = 3^2 + 4^2 = 25
c^2 = 5^2 = 25
Right triangle.
D.
a^2 + b^2 = 45^2 + 60^2 = 5625
c^2 = 75^2 = 5625
Right triangle.
Answer: 7, 12, 13
Answer:
0
Step-by-step explanation:
Hi there!
First, find g(4). Notice how on the first given table, when x=4, g(x)=9. Therefore, g(4)=9.
Then, find f(9). Notice how on the second given table, when x=9, f(x)=0.
Therefore, f(g(4)) is equal to 0.
I hope this helps!
The distance between two points is the number of units between them.
The distance between Q and R is 3.61 units
<em>It is impossible to determine your friend's error, because the steps are not given in the question. So, I will calculate the distance between Q and R, instead.</em>

The distance (d) between two points is:
So, the distance QR is:
Evaluate exponents
Take square root of 13
Hence, the distance between Q and R is 3.61 units

Answer:
x = 50°
Step-by-step explanation:
x + 20° + 30° = 180°
x = 180° - 20° - 30°
x = 130° (This one is other x)
x + 130° = 180°
x = 180° - 130°
x = 50°
