That is called supplementary angles, so they add up to 180 degrees
So it would be 57 + x + 23 = 180
Add 57 and 23, which is 80, subtract that from 180, and you would get
x = 100
2 tenths and 5 hundredths.
Answer: GN runs between a vertex and the midpoint of the opposite side, so it is a median.
HK is an altitude because it is perpendicular to base GJ and H is a vertex.
ML is not perpendicular to a base although it does bisect a base, but anyway, neither M nor L is a vertex: ML is neither altitude nor median.
Step-by-step explanation:
"A median of a triangle is a line segment joining a vertex to the midpoint of the opposing side, bisecting it. ... Each median divides the area of the triangle in half; hence the name" Wikipedia.
Yeah i agree with the question
Answer:
4x+x=360 (whole equation)
x=72 (answer)
Step-by-step explanation:
Let the distance driven by Jason be x.
Selena drove four times as far.
Hence, distance Selena drove is 4x.
They drove 380 miles altogether.
Hence, 4x + x = 380
5x = 380
x = 72
Hope this helped!
