Question

Is this right ? Geometry

Answer 1

No, 12 is the wrong answer. 5 is correct

This is because since a and c are congruent that means y=52. And we already know that every triangle adds up to 180 degrees so, you add A and C and get 104 (52+52).
And 180-104=76 so, 14x+6 must =76.
14(5)=70+6=76. 76+104=180, therefore, x=5.

Answer 2

Answer: 5

Explanation:

BA ≅ BC ⇒ ∠A ≅ ∠C

52 = y

The sum of the angles of a triangle equals 180°

∠A + ∠B + ∠C = 180

52 + 14x + 6 + 52 = 180

14x + 110 = 180

14x = 70

x = 5
