Answer

The measure of <QRX is 129⁰

Hence, m <QRX = 129⁰, which is the required answer.

Given:

In problem figure; angle RPQ = 49⁰,

angle PQR = 80⁰

To find:

m<QRX

Solution:

We know that sum of two interior angles of a triangle is equal to the sum of the exterior angle opposite to the interior angle

Thus, < RPQ + PQR = < QRX

Or, < QRX = 49⁰ + 80⁰

Or, < QRX = 129⁰
