Question

The answer and how to solve it​

Answer 1

x = 62.5 degrees.

Explanation:

As PQ = QT the triangle PQT is isosceles , so the base angles < QPT and <QTP (x) are equal.

So < QPT is x degrees also.

< PQT = 55 degrees (opposite angles) so, as there are 180 degrees in triangle PQT:

2x + 55 = 180

2x = 125

x = 62.5 degrees.
