The third angle of the triangle should be 37π/72 rad.
We need to know about the triangle rule to solve this problem. One of the rules of the triangle is the total angle inside the triangle is 180⁰.
A + B + C = 180⁰
From the question above, the given parameter is
A = π/9 rad
B = 3π/8 rad
Convert the angle to radian
180⁰ = π
Hence, the total angle should be
A + B + C = π
π/9 + 3π/8 + C = π
C = π - (π/9 + 3π/8)
C = π - 35π/72
C = 37π/72 rad
Hence, the third angle of the triangle should be 37π/72 rad

Answer:
Chemical energy
Explanation:
The energy in the torch is stored as chemical energy before the torch gets switch on.
The chemical energy energy in the battery of cell will power the cell and allows it to produce light.
- Chemical energy is a form of potential energy.
- The electrolytes within the battery are capable of producing electric current.
- So the chemical energy is transformed into electrical energy which is used to produce the light of the torch.
The density of a substance is the ratio of its mass to its volume. So whatever volume you have (call it ), the density is computed by
