Answer: 133</h3>
=============================================================
Explanation:
The quickest way to get this answer is to add the angles given to get 87+46 = 133
This is through the use of the remote interior angle theorem.
Note how the angles 87 and 46 are interior, or inside the triangle. And also, they are not adjacent to the exterior angle we want to find. So that's where the "remote" portion comes in.
----------------
The slightly longer method involves letting x be the measure of the missing interior angle of the triangle.
The three interior angles add to 180
87+46+x = 180
133+x = 180
x = 180 - 133
x = 47
The missing interior angle of the triangle is 47 degrees.
Angle 1 is adjacent and supplementary to this 47 degree angle, so,
(angle1)+(47) = 180
angle1 = 180-47
angle1 = 133 degrees
This example helps confirm that the remote interior angle theorem is correct.
Answer:
A'(7,-3)
Step-by-step explanation:
We were given the coordinates, A(-7,3) of quadrilateral ABCD and we want to find the image of A after a reflection across the x-axis followed by a reflection in the y-axis.
When we reflect A(-7,3) across the x-axis we negate the y-coordinate to obtain: (-7,-3).
When the image is again reflected in the across the y-axis, we negate the x-coordinate to get (--7,-3).
Therefore the coordinates of A' after the composed transformation is (7,-3).
