Answer:Division! :)
Step-by-step explanation:
that is true because all the sides would be the same if it was an equilateral triangle and a scalene triangle has no equal sides
Using ur calculator you should get 15 degrees ( Use the sin-1 key.).
Angle complementary to x is 90-15 = 75 degrees
and as sin x = cos(90-x) then cos 75 is also equal 0.2588
