Answer:
we have centre of circle as (30,40) and radius = 1
Step-by-step explanation:
Given that a car is moving on a circle on a plane.
At time t (seconds),
and
when we square and add both the equations we get
(since sin square + cos square = 1 always)
i.e. we have centre of circle as (30,40) and radius = 1
Answer:
x=30
Step-by-step explanation:
The two angles are supplementary. They add to 180
4x+20 + 40 =180
Combine like terms
4x+60 =180
Subtract 60 from each side
4x+60-60 = 180-60
4x = 120
Divide each side by 4
4x/4 = 120/4
x = 30
Answer:
A
Step-by-step explanation:
Using Pythagoras theorem, we have
x^2+11^2=15^2, x^2=104, x=2*sqrt(26)
