Let 
and 
.
And 
and 0 is rational.
Answer:
a = 3
b = 4
c = 5
Step-by-step explanation:
This is a rhombus. A property of a rhombus is that their diagonals perpendicularly bisect each other. In other words, if the point in the center is A, then HA = MA and EA = OA. So: 3 = a and 4 = b.
Since angle HAO forms a right angle, we can use the Pythagorean Theorem to say that HA^2 + AO^2 = OH^2: 3^2 + 4^2 = 9 + 16 = 25.
OH^2 = 25
OH = 5
Hope this helps!
Answer:
According to the graph, the answer would be the 5th month leading with 18 keychains but since I don't see that as an answer choice in the picture you provided, the answer would be the 4th month trailing close behind with a total of 16 keychains.
