Question

plz help this another two pics of the first picture ​

Answer 1

Answer:

angle PRQ = angle TRS

angle x = 50

now

angle QPR +angle PRQ + angle PQR = 180

by angle sum property of triangle

y + 40 + 50 = 180

y = 180- 90

= 90

in Triangle ABC

angle ACB + angle ACD = 180 ( linear pair property)

angle ACB + 130 = 180

angle ACB = 180 - 130

= 50

but it is given that AB = AC

so , angle ABC = angle ACB

therefore angle ABC = 50 , x = 50

now ,

angle ACB + angle ABC + angle BAC = 180

by angle sum property of triangle

50 + 50 + y = 180

y = 180 - 100

y = 80

i hope this will helps you

Answer 2

Answer:

y = 80°

hope this helps to you
