Question

For what value of x is triangle ABC congruent to triangle DEF?

Answer 1

Answer:

12

Step-by-step explanation:

7x+10=94

   -10    -10

7x=84

7x/7=84/7

x=12

4x-6=42

    +6  +6

4x=48

4x/4=48/4

x=12

Answer 2

Answer:

a. 12

Step-by-step explanation:

Congruent in this sense would mean all angles are equal. If that's the case, we could set up this equation to solve for x:

7x + 10 = 94

7x + 10 being triangle ABC and 94 being DEF, they're congruent so I set them equal to each other.

To solve:

7x - 10 = 94 - 10

7x = 84

7x/7 = 84/7

x = 12
