So, an isosceles triangle has 2 equal sides, we will call them x.
The base can be modeled by 3+x
So, the perimeter is equal to x + 3+x + x
So
15.6 = 3x + 3
12.6 = 3x
4.2 = x
So, the lengths of the sides are 4.2, 4.2, 7.2

Answer:
option C is correct
Step-by-step explanation:
We need to find the determinant.
= -1(7*9 - 3*9)-( -3)(4*9 - 3*3) -2(4*9 -7*3)
= -1(63-27) +3 (36 - 9) -2( 36- 21)
= -1(36)+3(27)-2(15)
= -36+81-30
= 15
