Well really it would have to depend on the flashlight. Is it an led bulb or a regular bulb?
Because it is a 90° angle and the legs are congruent, the legs intersect with the hypotenuse at the same angle, so the other, unnamed angle at the bottom left is equal to x.
Now we can state that:
2x + 90 = 180
2x = 90
x = 45
collect the like terms:
Solution: x^2-5xy+4y
P.S
get the photo math app. :)
Hope that helps.
Will there's
5.5 x 2 = 11
hope that helped
