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°.
You have to change the denominator of 6/10 into 100 then you will get 60/100 then you add 15/10+60/100
You don't need to regroup when adding a two-digit number with a number.
