Similar triangles have equal angles. I mean, if two triangles
are similar, then the angles of one triangle are the same as
the angles of the other one.
The triangle in the question has angles of 20° and 40°.
The angles of every triangle add up to 180°, so we know
that the third angle has to be 120°
If another triangle is similar to this one, then the other one
also has angles of 20°, 40°, and 120°.
Answer:
C 11
Step-by-step explanation:
2y = 12 – 5x
Let x = -2
2y = 12 - 5(-2)
2y = 12 +10
2y = 22
Divide by 2
2y/2 = 22/2
y = 11
Answer:
A. No, it does not pass the vertical-line test..
Step-by-step explanation:
A. is the correct answer, as functions cannot have the same x value correspond to different y values. For a function to be considered a function, it must always pass the vertical line test.
