Atriangle has two angles measuring 42 and 73 calculate the third angle of the triangle

The measure of third angle of the triangle is 65°

Step-by-step explanation:

Measure of one angle of the triangle is given to be 42

Measure of second angle of the triangle is given to be 73

Let the measure of the third angle of the triangle be x

Now, By using the angles sum property of a triangle, We have :

Sum of all the three angles of a triangle is always supplementary

⇒ ∠1 + ∠2 + ∠3 = 180°

⇒ 42° + 73° + ∠3 = 180°

⇒ 115° + ∠3 = 180°

⇒ ∠3 = 180° - 115°

⇒ ∠3 = 65°

Hence, The measure of third angle of the triangle is 65°

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
