The angle of the triangle ABC from smallest to largest are approximately 22°, 27° and 131°.
The sides of the triangle are as follows;
AB = 20
BC = 12
AC = 10
Let's find ∠A using cosine rule,
a² = b² + c² - 2bc cos A
cos A = b² + c² - a² / 2bc
Therefore,
cos A = 10² + 20² - 12² / 2 × 10 × 20
cos A = 100 + 400 - 144 / 400
cos A = 356 / 400
cos A = 0.89
A = cos⁻¹ 0.89
A = 27.1267531173
∠A ≈ 27°
Using sine rule let's find ∠B
12 / sin 27 = 10 / sin B
cross multiply
12 sin B = 10 sin 27
sin B = 10 sin 27 / 12
sin B = 10 × 0.45399049974 / 12
sin B = 4.5399049974 / 12
B = sin⁻¹ 0.37832541645
B = 22.2299936087
∠B = 22°
Using sum of triangle theorem let's find ∠C
∠C = 180 - 27 - 22
∠C = 131°
The angles from smallest to largest are approximately 22°, 27° and 131°.

How are the nervous systems of a flatworm and a fish different?
A flatworm has a simple nervous system with two nerve cords running down both of its sides. It also has two simple brains, and two eyespots that help sense light. While a fish's nervous system is comprised of a central brain and a spinal cord along with many branching nerves, which allows them to sense things around them.
Explanation:
A flatworm has a very mild nervous system with pair nerve cords moving down each side. It has two single brains called ganglia, which are pure packages of nerves. It has two eyespots that support it sense light. A flatworm has a gastrovascular hole with one opening.
Fish have extremely advanced nervous systems organized around a brain. Fish brains have rare clearly visible parts. Back to the brain is the spinal cord, which is the deep dorsal nerve cord that identifies chordates.
