Question

In $△$ XYZ , $\overline{XY}$ =6.3 cm and $\overline{XZ}$ = 7 cm. Which is the correct information needed to construct the triangle?

• A. $\angle$ X = 85°
• B. $\angle$ Y = 50°
• C. $\angle$ Z = 45°
• D. None of the above

Answer 1

The correct option is A $\angle$ X = 85°

The two sides $\overline{XY}$ and $\overline{XZ}$ are given. According to SAS criteria, if we get the value of the included angle $\angle$ X , then we can construct the $△$ XYZ
