Answer:
85
Step-by-step explanation:
60+60+70+80+85 = 355
355/5 = 71
Answer:
(5*sqrt(2), 5pi/4)
Step-by-step explanation:
In Polar coordinates, tan(theta)=y/x and r=sqrt(x^2+y^2)
tan(theta)=-5/5=-1. Theta=5pi/4
r=sqrt(5^2+5^2)=5*sqrt(2)
Hence the Polar coordinate is (5*sqrt(2), 5pi/4)
21x-33°=180°-135°
21x=12°
x=12/21
7x (2x^2 - 3) is your answer my dude/lady
