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

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

i wish i could you, i have no idea how to answer this
