Answer:
<6 = 60 degrees, <7 is 50 degrees, <8 is 70 degrees
Step-by-step explanation:
Angle 6 is 60 degrees because of the alternate interior angles theorem.
Angle 7 is 50 degrees, also because of the alternate interior angles theorem.
Now, the three interior angles of a triangle should add up to 180 degrees. That means:
60 + 50 + <8 = 180
<8 = 70 degrees
<6 = 60
<7 = 50
<8 = 70
My answer -
1609.344m

Happy to help you have an AWESOME!! day :D
Answer:
Option B.
Step-by-step explanation:
If two lines are parallel then their slopes are always same.
Following this rule we can find the slope by the given pairs of coordinates of the options.
If the slope of the line is same as the slope of y axis then the line passing through these points will be parallel to the y axis.
Slope of y - axis = ∞
Option A). Slope =
=
=
= 775
Therefore, line passing through points (3.2, 8.5) and (3.22, 24) is not parallel to y axis.
Option B). Slope of the line passing through and will be
=
= ∞
Therefore, line passing though these points is parallel to the y axis.
Option C). Slope of the line passing through and (7.2, 5.4)
=
= 0
Therefore, slope of this line is not equal to the slope of y axis.
Option B. is the answer.
True, In Euclidean geometry an equilateral triangle must be a 60-60-60 triangle.
Hope This Helps!!!
