Answer:
x = 5 and y = 8.7
See attached image for working
Step-by-step explanation:
Since it's a right angle triangle you can use sin and cos.
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)
Answer:
x = 9
Step-by-step explanation:
-4(6x+3)=-12(x+10)
-24x-12=-12x-120
+12 +12
-12x=-12x-108
/-12 /-12 / -12
x=9
Answer x=9
Put 1.12 on top and times regullarly you should get 1280.00
