Question

in triangle pqr , qr = pr and <q = 40° then find <r​

Answer 1

Answer:

<r = 100°

Step-by-step explanation:

If qr = pr, q = p

Therefore, <p = 40° if <q = 40°

Since the sum of the angles of a triangle is 180°,

<q + <p + <r = 180°

40° + 40° + <r = 180°

               <r = 180° - 40° - 40°

               <r = 180° - 80°

              <r = 100°
