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:
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
