The two guy wires supporting a tower form an isosceles triangle with the ground. each of the base angles of the triangle is 2 times the third angle (the vertex angle). find the measure of the vertex angle.

The measure of the vertex angle is 36 degrees.

Step-by-step explanation:

In order to find this, we set the vertex angle as x and the base angles as 2x. Now we can add all three angles together and set equal to 180.

x + 2x + 2x = 180

5x = 180

x = 36

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

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
