HOPE THIS HELPS!!!!!!
Answer:
180°- 3α
Step-by-step explanation:
By angle sum postulate of a triangle.
Everyone should do this derivation, because otherwise the "quadratic formula" is some sort of "magic" LOL...
ax^2+bx+c=0
x^2+bx/a+c/a=0
x^2+bx/a=-c/a
x^2+bx/a+b^2x/(4a^2)=b^2/(4a^2)-c/a
(x+b/(2a))^2=(b^2-4ac)/(4a^2)
x+b/(2a)=±√(b^2-4ac)/(2a)
x=-b/(2a)±√(b^2-4ac)/(2a)
x=(-b±√b^2-4ac)/(2a)
Answer:
-10x + 1.5
Step-by-step explanation:
If both are similar ratio of sides will be same
