1,3,4 just match the markings.
Changes in a coordinate
can be observed with 90 degree rotations about the origin.
90 degrees CW =
180 degrees CW =
270 degrees CW =
Let's observe M(10, 12) and M'(12, -10).
Since they switched and the x value became negative, it must have been a
90 degree rotation.
Answer:
She can buy 7 Journals
Step-by-step explanation:
9 + 3x ≤ 30
Subtract 9 on both sides...
3x ≤ 21
Divide by 3 on both sides...
x ≤ 7
Hope this helps :)
The measure of angle 4 is equal to the sum of the measures of the two nonadjacent interior angles because the angle 4 is exterior to the given interior angles.
<h3>Exterior angles of a triangle</h3>
The sum of interior angles is equal to the exterior. From the given figure;
Interior angles are 25 degrees and 52 degrees.
The measure of angle 4 is equal to the sum of the measures of the two nonadjacent interior angles because the angle 4 is exterior to the given interior angles.
2) <4 = 25 + 52
<4 = 77 degrees
Hence the measure of angle 4 is 77 degrees
