Classify the following triangle. Check all that apply. A. Scalene B. Right C. Acute D. Equilateral E. Obtuse F. Isosceles ​
Sati [7]

Answer:

E and F

Step-by-step explanation:

The triangle given has two equal sides, and an obtuse angle that is more than 90° that measures 120°. The other two angles are of equal measure since their opposite sides are of the same length. Thus, this implies that it is an isosceles triangle because it has two equal base angles and two equal sides. It also implies that it is an obtuse triangle since one of it's angles is more than 90°.

Which is an equation of a direct proportion?<br> y=16x+6<br><br> y=6x<br><br> y=6x−6<br><br> y=6x
natita [175]

The model for direct proportion is y = mx.  Note that there is no "offset," no "y-intercept."  

y = 6x represents direct proportion with a constant of proportionality 6.  The other 2 choices are disqualified because of offset +6 or -6.
