Answer:
46
Step-by-step explanation:
72 + 58 + 2x + 3x = 360
5x = 230
x = 46
Answer:
4/5
Step-by-step explanation:
Sin = Opposite / Hypotenuse
Note that hypotenuse = longest side
We want to find sinФ
The opposite side length of angle "Ф" has a length of 8 and the longest side or hypotenuse has a length of 10
So sinФ would equal 8/10 which can be simplified to 4/5
Answer:
x y
-6 11
3 5
15 -3
-12 15
Step-by-step explanation:
just use substitution
If you have found the coordinates, then the distance
between the points is just
√(difference in the Xs)² + (difference in the Ys)² .

Part 2: No.
From the equation of the circle, the center is at the origin,
and the radius is 5.
Reason #1:
==> Since the distance between your points A and B is not 10,
AB can't be a diameter of the circle.
(If you got 10 or more for the length of AB, you made a mistake on the
coordinates of A or B, or on the distance between them.)
The line Y=1-x does not go through the origin.
(Write it as Y = -x + 1 . The Y-intercept is 1, not zero.)
Reason #2:
==> Since and the line AB doesn't go through the origin and the circle
is centered at the origin, AB doesn't go through the center of the circle,
so it can't be a diameter of the circle.
Answer:
52 minutes
Step-by-step explanation:
This should be a proportional statement, because if each individual person painted there own wall it should still take 52 minutes.
