Answer:

The answer is the third one: x + y + z = 180 degrees

Step-by-step explanation:

in the picture we can tell angle x measures 90 degrees meaning that the third angle of the triangle also measures 90 degrees because the sum of the angles of a triangle is always 180 we can be sure that x + y + z = 180 degrees

Answer:

y + z = x

Step-by-step explanation:

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

x is an exterior angle of the triangle, thus

y + z = x

1. Is it proportional?
astra-53 [7]

Answer:

Y=5(x) Yes it is porportional.

Step-by-step explanation:

So lets look at the graph.

We first have 1x = 5y

Well, that makes it seem like for each x there are 5 y.

Lets see the other values:

2x = 10y

Divide both sides by 2 tog et x alone:

1x=5y

Again, for each x, there are 5y.

This is true for each one:

3x=15y

=

1x=5y

4x=20y

=

1x=5y

5x=25y

=

1x=5y

and finally:

6x=30y

=

1x=5y.

So yes, this is poroportional.

It can be shown as x=5y, since for a single x, there are 5 y's.

Hope this helps!
