Answer 2

${\tt {\red {\underline{\underline {\huge {Answer}}}}}}$

$\large\underline\mathrm{GiVeN}$

• Ratio of Angles = 2:7:5:4

$\large\underline\mathrm{To FiNd}$

• All angles of polygon

$\large\underline\mathrm{We KnOw}$

• Sum of all angles of quadrilateral= 360°

$\large\underline\mathrm{SoLuTiOn}$

Let the angles be 2x,7x,5x and 4x

According to question,

➨2x+ 7x +5x +4x = 360°

➨18x = 360°

➨ x = 360 /18

➨x =20°

Angles of polygon,

2x = 2 × 20 = 40°

7x = 7 × 20 = 140°

5x = 5 × 20 = 100°

4x = 4 × 20 = 80°

Therefore, angles are 40°, 140°, 100°and 80°.
