Answer:
Angle 4 = 135, angle 5 = 45
Step-by-step explanation:
Consecutive interior angles are supplementary, therefore angle 5 + angle 8 = 180 degrees. Since the complement of 5 is the supplement of 4, we can write the system of equations.
180 - x = 90 - y or -x + y - 90 - 180 or -x + y = -90 or x - y = 90
x + y = 180
x - y = 90
Where angle 4 is x and angle 5 is y.
y = 180 - x
x - (180 - x) = 90
x - 180 + x =90
x + x = 270
2x = 270
x = 135
By plugging that in to an equation we can solve for y.
y = 45
Answer:
4.95238095238= x
Step-by-step explanation:
-87= 3(6-7x)
-87= 17-21x
-17 -17
-104= -21x
/-21 /-21
4.95238095238= x
The first one is true, so is the fourth one. The second one is not true and I'm not sure about the 3rd one, you would have to write them all out in numerical order and find the one in the middle
Answer:
0.9412
Step-by-step explanation:
Ultimately, if you know the length of the arc, and you know the length of the radius, the central angle (in radians) is just how many radii long the arc is. angle=arc lengthradius length=16 feet17 feet≈0.9412.
(1,-1)(2,2)
slope = (2 - (-1) / (2 - 1) = 3/1 = 3
y = mx + b
slope(m) = 3
use either of ur points...(2,2)...x = 2 and y = 2
now we sub and find b, the y int
2 = 3(2) + b
2 = 6 + b
2 - 6 = b
-4 = b
so ur equation is : y = 3x - 4
