Question

in triangle pqr angle P is equal to 80 degree angle Q is equal to 30 degree then find r

Answer 1

Answer:

r=70

Step-by-step explanation:

Answer 2

Answer:

<r = 70°

Step-by-step explanation:

In triangle sum of all angles is 180° degree.

Therefore,

<p + <q + <r = 180°

80° + 30° + <r = 180°

110° + <r = 180°

<r = 180° - 110°

<r = 70 degrees
