DO ANYONE KNOW HOW TO DO DILATIONS..I NEED HELP.ILL GIVE BRAINLEST AND POINTS
1 answer:
Answer:
C' = (2, 1)
Step-by-step explanation:
The co-ordinates of C from the graph is: C(6, 3).
When a co-ordinate is dilated by a factor, say 'a' then each term in the co-ordinate is dilated by 'a'.
Therefore, here, we will have: (6, 3)
= (2, 1)
Call this C'. Therefore, the co-ordinate of C' = (2, 1).
Hence, the answer.

Answer:
Step-by-step explanation:
<h3><u>Given that:</u></h3>Exterior angle of L = 5x + 12
M = 3x - 2
N = 50
<h3><u>Statement:</u></h3>- Exterior angle is equal to the sum of non-adjacent interior angles.
So, the exterior angle that is adjacent to L is equal to the sum of non-adjacent sides (M and N) of the triangle.
Here,
Exterior angle of L = M + N
5x + 12 = 3x - 2 + 50
5x + 12 = 3x + 48
Subtract 12 to both sides
5x = 3x + 48 - 12
5x - 3x = 36
2x = 36
Divide 2 to both sides
x = 18
So,
<h3><u>Measure of angle M:</u></h3>= 3x - 2
= 3 (18) - 2
= 54 - 2
= 52°
Now,
<h3><u>Measure of angle L:</u></h3><u>We know that,</u>
- Sum of all the interior angles of triangle is 180 degrees.
L + M + N = 180°
L + 52 + 50 = 180
L + 102 = 180
Subtract 102 to both sides
L = 180 - 102
L = 78°
