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
