Find the value of x and y that make these triangles congruent by hl.

 the correct option is (A) x = y = 2.

Step-by-step explanation:  We are given to find the values of x and y that makes the triangles in the figure congruent by HL.

From the figure, we note that

triangles ABC and AED are right-angled triangles with hypotenuse AC, AD and one congruent side BC, ED.

Also, AC = 2x + 3, AD = 3y+1, BC = x  and  ED = y.

Since the triangles are congruent by HL postulate, so we must have

Substituting the value of x from equation (i) in equation (ii), we get

So, from equation (i), we arrive at

x = y = 2.

Thus, the correct option is (A).

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
