Question

Find m∠QST.
1.) 7.5 Degrees
2.) 15 degrees
3.) 30 degrees
4.) 75 degrees

(Pic attached below)

Answer 1

They are both right triangles. Hypotenuse is same (SQ). Bases are equal in length (QR = QT). So, they must be identical right triangles. So, if QSR is 15 degrees, angle QST must also be 15 degrees.

Answer 2
