The common denominator of these fractions will be 12. So Ann worked 306/12 hours, Mary worked 244/12 hours, and John worked 123 hours, meaning they have worked 673/12 hours together.
Answer:
C
Step-by-step explanation:
Plotting the points in a sketch quickly shows that the vertices are not at right angles to each other, thus excluding rectangle and square whose vertices are at right angles.
The best selection is a rhombus
remember the pythagorean theorem:
a² + b² = c²
where c is the hypotenuse.
so:
the square and the square root cancel each other out, so...
a² + b² = 26
we know that a and b are of equal length given the angles.
so it's
here the squares and square roots also cancel, but to keep the equation from the formula true we need to write them. that makes the difference between optional and B
Option A is correct,
