Step-by-step explanation:
3(−3x2+5x)
=(−3)(−3x2+5x)
=(−3)(−3x2)+(−3)(5x)
=9x2−15x
Answer:
120 degrees is the right angle and the 30 degree added which is 1/3 here we know as we can always divide a side measure by 90 then multiply by a second angle to find the hypotenuse. When we do this we are using a three way system just like a three way system appears when we use a right angle triangle and read the functions.
