Answer:
Hello! answer: 40
Step-by-step explanation:
This is a supplementary angle meaning it will have a total of 180 degrees 4 × 40 = 160 and when you add that with the other angle 20 you get 160 + 20 = 180 therefore x must by 40 HOPE THAT HELPS!
Answer: The angles of ΔA'B'C are congruent to the corresponding parts of the original triangle.
Step-by-step explanation:
Given : Triangle ABC was rotated 90 degrees clockwise. Then it underwent a dilation centered at the origin with a scale factor of 4.
A rotation is a rigid transformation that creates congruent images but dilation is not a rigid transformation, it creates similar images but not congruent.
Also, the corresponding angles of similar triangles are congruent.
Therefore, The angles of ΔA'B'C are congruent to the corresponding parts of the original triangle.
Step-by-step explanation:
percentage of green marbles=
(total green marbles÷ total marbles )×100
17=5k-2
add 2 to both sides
19=5k
divide both sides by 5
19/5=k
19/5=3 and 4/5
