Answer:
1/5
Step-by-step explanation:
Blue mables: 3
green and red marbles: 8 + 7 = 15
then, the radio blue:(green+red) is:
3 : 15
simplified unit rate is:
3/3 = 1
15/3 = 5
then:

Which of these triangle pairs can be mapped to each other using a single reflection?
Triangles F E G and F G L are congruent. Triangle F E G is reflected across line F G to form triangle F G L.
Triangles F E G and G L M are congruent. Triangle E F G is rotated about point G to form triangle G L M.
Triangles F E G and L M N are congruent. Triangle F E G is shifted down and to the right to form triangle L M N.
Triangles L M N and E F G are congruent. Triangle F E G is reflected across a line to form triangle L M N. Triangle L M N is also slightly higher and to the right of triangle E F G.

(PLEASE ANSWER!) Two distinct lines, L and M, are each perpendicular to the same line N. What is the measure of the angle where line L meets line N? What is the measure of the angle where line M meets line N?
Answer:
90 and 90
Step-by-step explanation:
If they are perpendicular it means they cross at a 90 degree angle so since both L and M are perpendicular to N both the answers would be 90
Hope This Helps :)
The measure of the angle where line L meets line N is 90° ;
and the measure of the angle where line M meets line N is 90°.
What are perpendicular lines?In geometry, perpendicular lines are defined as two lines that meet or intersect each other at right angles (90°).
Now it is given that,
Two distinct lines, L and M, are each perpendicular to the same line N.
Line L is perpendicular to line N.
Since angle between two perpendicular lines = 90°.
So, angle between line L and line N = 90°
Similarly, Line M is also perpendicular to line N.
Therefore, angle between line M and line N = 90°
Thus, The measure of the angle where line L meets line N is 90° ;
and the measure of the angle where line M meets line N is 90°.
