Iam a 2 dimensional shape that has 3 acute angles. all my sides are the same length. i have no parallel sides

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.

plzz mark brainlest last one got deleted. cause i didn't explain it but i did but i understand what the mod meant

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two
