Answer:
The equation is 12x=180. You worked for 15 hours.
Step-by-step explanation:
Do 12x=180 then divide by 12. You get x=180/12. Then simplify
Answer:
A
Step-by-step explanation:
Note
One thing you should automatically notice is that x is larger, much larger than 20. x is the hypotenuse of a right triangle
Formula
Sin(18) = opposite side / hypotenuse
Givens
Sin(18) = 0.30902
opposite = 20
hypotenuse = x
Solution
sin(18) = 20 / x Multiply both sides by x
x sin(18) = 20*x /x
x sin(18) = 20 Divide by sin(18)
x sin(18) / sin18 = 20/sin(18)
x = 20 / 0.30902
answer: x = 64.72
Answer:
Centre is 
Radius is 
Step-by-step explanation:
The general equation for a circle is written in the form
, where
is the centre of the circle, and
is the radius.
For your circle,
, we can compare it with the general equation to find the centre and radius.



Therefore,
,
and
.
Centre at
which is
.
