Answer 2

Answer:

<p = 100°

<s= 80°

<r= 110°

<q= 110°

Step-by-step explanation:

given = ABCD is quadrilateral and

<A = 70° , < B= 100° , <C = 80°

to find - angle p, q, r and s

solution- AD is line so,

<A + <r = 180°

70°+<r=180°

<r= 180°-70°

<r= 110°

similarly,

<B +<s = 180

<s = 180-100

<s= 80°

similarly,

<c + <p = 180

<p= 180-80

<p = 100°

sum of interior angles of quadrilateral is 360

in quadrilateral ABCD

<A+<B+<C+<D= 360

70°+100°+80°+<D = 360

250+<D = 360

<D = 360-250

<D= 110° or <q = 110°
