Question

abcd is a quadridateral in with angle a 50 angle b 70 angle c 80 find d​

Answer 1

Given :-

∠A = 50°

∠B = 70°

∠C = 80°

Find :-

∠D = ?

Solution :-

Sum property of quadrilateral angles = 360°

Now add the angles to find ∠D :-

∠A + ∠B + ∠C + ∠D = 360°

50° + 70° + 80° + ∠D = 360°

200° + ∠D = 360°

∠D = 360° - 200°

∠D = 160°

Result is :- ∠D = 160°
