For what values of x and y are the triangles congruent? a. x=-4, y= -4 b. x=-4, y= 4 c. x=4, y= 7 d. x=7, y=4

The answer is the option D

Step-by-step explanation:

we know that

If the triangles are congruent

then

The corresponding sides are congruent

substitute the values

-------> --------> equation A

-------> ------->

Substitute the value of y in the equation A and solve for x

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
