Answer 1

HEYA MATE, HERE IS UR ANSWER


$<b><i>We know that Each Angle of equilateral triangle =60 degree$


Angle of square=90 degree


So Angle TRQ=angle TRS + angle SRQ


TRQ=60+90


TRQ=150 degrees


In triangle TQR

TR=RQ (as SR=RQ=TR)

so angle TQR=QTR(angle opposite to equal sides are equal )-----(1)

so angle TRQ+TQR+RTQ=180 (angle sum property of a triangle )

150+TQR +TQR =180 (from 1)

150+2TQR=180

2 TQR=180-150

2TQR =30

angle TQR =$\frac {30}{2}$

angle TQR=15


Hence Proved

$\huge\boxed{\mathbb{BE\:BRAINLY}}$
