Which statements are true? Check all that apply.

1. m =120° , m =60°¬ (incorrect) ⇒if you are considering a triangle sum of three angles should be 180°. Here sum of two angles is 180. Second thing you can't name the angles of a triangle by small letters.Thirdly two angles can't have same measure.

2.m∠COB = 2(m∠CAB)  ¬ Correct

Consider a triangle COB , AB being the base and O at a certain distance from A.So in this case this possibility is sure to happen.Shown through a diagram

3.m∠COB = 120° ¬ Correct ⇒Consider a triangle COB,∠COB can be obtuse.So we call it obtuse angled triangle.

4.m∠COB = m∠CAB ¬ Correct

To prove this i have given a diagram below.

Step-by-step explanation:

Hope it helps!

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
