Question

In given figure, if lines PQ and RS intersect at point I, such that ZPRT = 40°, ZRPT = 95º and
ZTSQ=75, find Z SQT.
​

Answer 1

Answer:

60°

Explanation:

PRT+RPT+PTR=180°

40°+95°+PTR=180°

PTR=180°-135

PTR=45°

TSQ+STQ+SQT=180°

75°+45°+SQT=180°

120°+SQT=180°

SQT=180°-120°

SQT=60°
