Answer 1

sum of all interior triangle is 180degree

in triangle PQS

50+90+angle p=180

140+p=180

p=180-140

p=40 degree. 1)

in triangle PQR

50+30+p=180

p=180-80

p=100. 2)

in triangle PST

t+X+90=180

t=90-X

T=P

90-X (,ALTERNATE ANGLE ARE EQUAL)

40+X+(90-X)=100

40+X+(90-X)(90-X)=100

40+X+[(X)2-2(90)(×)+(90)2=100

40+X+X2-180X+8100=100
