The sum of two numbers is 42 and the difference is 20. What are the numbers?

4. Katy sells new video games at a gaming store. Katy gets a bonus if she sells more than 60 video games. If 8 people each buy 7

8 people each buy 7 so, 8 x 7 = 56
She needs to sell 60:
60 - 56 = 4
Katy is 4 away from selling 60.

Triangle ABC is an equilateral triangle.Find the angle of rotation that maps A to B

svet-max [94.6K]

The sum of the inner angles of any triangle is always 180°, i.e. you have

$\alpha + \beta + \gamma = 180$

In the particular case of an equilater triangle, all three angles are the same, so

$\alpha = \beta = \gamma$

and the expression becomes

$\alpha + \beta + \gamma = \alpha + \alpha + \alpha = 3\alpha = 180$

which implies $\alpha = 60$

So, if you rotate the triangle with respect to its center by 60 degrees, the triangle will map into itself. In particular, if you want point A to be mapped into point B, you have to perform a counter clockwise rotation of 60 degrees with respect to the center of the triangle.

Of course, this is equivalent to a clockwise rotation of 120 degrees.

Finally, both solutions admit periodicity: a rotation of 60+k360 degrees has the same effect of a rotation of 60 degrees, and the same goes for the 120 one (actually, this is obvisly true for any rotation!)
