PLZ HELP!! The length of each side of the two congruent sides of an isosceles triangle is 5n + 3 and the length of the third side is 4n. Write TWO equivalent expressions for the length of the perimeter of the triangle.

Step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
