The points on this graph represent a relationship between r- and y-values. Which statement about the relationship is true?
(0,0)
CLEAR
CHECK
It cannot be proportional because no values are given.
It cannot be proportional because the straight line through
the points does not go through the origin.
O
It must be proportional because each time x increases by
3 units, y increases by 1 unit.
It must be proportional because the points lie in a straight
line.

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
