Answer:
the value of x would be 108 degrees
Step-by-step explanation:
The computation of the value of x in degrees is shown below:
Given that both the triangles has the 34 degrees and 48 degrees
Now in the triangle 1 angle a = 108 degrees
And, in the triangle 2 a = x
Now in this case both the triangles are similar to each other
So here the value of x would be 108 degrees
This represent the refute the claim of Bob
I think maybe 3) would make the most sense because she wants a random sample of students and the other options are specific on the type of students.
Answer:
Step-by-step explanation:
x < 12
Options are not shown but…
A square has 4 equal length sides and a right angle
Or two equal length diagonals which are perpendicular
Or 4 right angled corners and two adjacent sides equal
Or perpendicular diagonals with the same midpoint
Using the last one…
Gradient of AC = (5 - 3)/(-3 - 3) = 2/-6 = -1/3
Gradient of BD = (7 - 1)/(1 - -1) = 6/2 = 3
-1/3 x 3 = -1 so AC and BD are perpendicular
Midpoint of AC = ((-3 + 3)/2 , (5 + 3)/2) = (0, 4)
Midpoint of BD = ((1 + -1)/2 , (7 + 1)/2) = (0, 4)
