Answer 2

In the given figure,
In triangle SQR
angle S = 70
and SQ = SR
Angle Q = Angle R
And we know that sum of all the angles of triangle is 180
so, angle S +Angle Q +Angle R=180
x= 55
Angle Q = 55
Angle R =55
Angle S =70
NOW in triangle PQR
Angle P = 30
and we know that angle Q and angle R is equals so,
Angle Q = 55+x
Angle R = 55+ x
now in triangle PQR
ANGLE P + ANGLE Q+ ANGLE R= 180
140 + 2X = 180
X = 20
AND
ANGLE PQR = 75
ANGLE PRQ = 75
ANGLE SQR = 55
ANGLE SQR = 55
VALUE OF X = 20
