Question

If triangle ABC is congruent to DEF, what is the value of x?

Answer 1

Determine the measure of angle A in triangle ABC.

`\begin{gathered} \angle A+\angle B+\angle C=180 \\ \angle A=180-56-48 \\ =76 \end{gathered}`

The triangle ABC is congruent to traingle DEF. So

`\begin{gathered} \angle D=\angle A \\ x=76 \end{gathered}`

Thus value of x is 76 degree.
