Answer:
28

28 = 7 x 4
So,

4 * 45 = 180
265 - 180 = 85
85/5 = 17

Answer: No
In right triangle we have 30:60:90
and the ratios are
x: x root of 3: 2x
so, for example, if we have side of length 3 against 30 degrees, then against 60 degrees the side will be 3 root of 3, and against 90 degrees it will be 6.
Hope it helps!
