Answer 1

Answer:

90

Step-by-step explanation:

60 70 80 and 90 its soooo simple

Answer 2

Answer:

Let , ABCD is the quadrilateral

Step-by-step explanation:

Given,

<A = 70°

<B = 60°

<C =80°

We have to find ,

<D= ?

So, we know that

Sum of all angles of an quadrilateral is 360°

Now,

<A + < B + <C + <D = 360°

=> 70° + 60° + 80° + <D = 360°

=> 210° + <D = 360°

=> <D = 360° - 210°

=> <D = 150°
