<span> 90°-41.4°=48.6°
Complementary angle is 48.6°.
180°-41.4°=138.6°
</span><span>Supplementary angle is 138.6°.

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: $4.92
Step-by-step explanation: If Sam had 4 candy bars and they cost $1.23, you multiply 4 by 1.23 to get $4.92—The total amount that Sam spent
