Step-by-step explanation:
1.sin 45 = 1/
sin theta = opposite side/hypotenuse
opposite side/hypotenuse = 1/
12/hypotenuse = 1/
hypotenuse = 12
cos 45 = 1/
adjacent side/hypotenuse = 1/
adjacent side/12 = 1/
adjacent side = 12
Therefore the sides are 12,12,12
2.Perimeter = 12+12+12 = 24+12
= 24 + 12(1.414) =24 + 16.9 = 40.9cm
I hope it help please mark me as brainliest...
