180°= 14x + 7 + 20x + 8 what is the = of x

The answer is:    " x  =  4.853 " .

Explanation:

To solve:

Given:   " 180  =  14x  +  7  +  20x  + 8 "  ;   Solve for "x" .

From the "right-hand side" of the equation;  combine the "like terms" ; as follows:

   + 14x  + 20x  =  + 34x  ;

   +  7  +  8  = + 15  ;

and rewrite:

 180 =  34x + 15  ;

 ↔  34x  +  15  =  180 ;

Subtract "15" from EACH SIDE of the equation; as follows:

       34x  + 15  −  15  =  180 − 15  ;

to get :

       34x   =  165   ;

Now, let us divide EACH SIDE of the equation by "34" ;

to isolate "x" on one side of the equation; & to solve for "x" ; as follows:

       34x  / 34  =  165 / 34  ;

to get:

            x  =  4.8529411764705882  ;  round to: " 4.853 "   .

The answer is:  " x = 4.853 " .

i think it is c, not positive though

step-by-step explanation:

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
