Answer:
angle R =70
Explanation:
angles in a triangle add up to 180°
to find angle TQP add known angles and subtract from 180
57+75=132
180-132=48
angles in a straight line add up to 180°
use new found angle and known angle to find angle SQR
48+48=96
180-96=84
angles in a triangle add up to 180°
to find angle R add known angles and subtract from 180
26+84=110
180-110=70
