Step-by-step explanation:

this is the answer to your question

Answer 2

Step-by-step explanation:

in a quadrilateral sum of angles = 360°.

and the angles are sharing ratio in 1:2:4:5.

sum of ratios is 12.

so,

∠a = 360°/12×1=》30°.

∠b = 360°/12×2=》60°

∠c = 360°/12×4=》120°

∠d = 360°/12×5=》150°.
