Find the value of x (Angles)

x = 83

Step-by-step explanation:

The two angles form a right angle, which is 90 degrees

25+ x-18 = 90

Combine like terms

x +7 =90

Subtract x from each side

x+7-7=90-7

x = 83

Hello! x = 83

Step-by-step explanation:

This is a Complementary angle meaning it will add up to 90 degrees so...

83 - 18 = 65 65 + 25 = 90 therefore x = 83 Hope that helps!

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.
