For what values of x and y are the triangles to the right congruent by​ HL?
vaieri [72.5K]

Answer:

x = 28/3

y = 7/3

Step-by-step explanation:

If the triangles are congruent, then corresponding sides are equal.

x = 4y

x + 1 = y + 8

Solve the system of equations using substitution or elimination.  Using substitution:

4y + 1 = y + 8

3y = 7

y = 7/3

Solving for x:

x = 28/3

Solve the following equation to determine the value of x: 3x + (x + 10) + 5x + (2x + 2) = 56
nika2105 [10]

Answer:

I think x = 4.

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3x + x +10 + 5x + 2x + 2 =56

(3x + x + 5x + 2x) + (10 + 2) = 56 (Combine Like Terms)

11x + 12 = 56

11x + 12 = 56

Step 2: Subtract 12 from both sides.

11x + 12 − 12 = 56 − 12

11x = 44

Step 3: Divide both sides by 11.

11x/11 = 44/11

x = 4
