Answer 2

Given :

• The given image ABCD.
• A = 70°,
• B = 80°,
• C = 70°,
• D = "x".

ㅤㅤ

Find :

• Find the value of x.

ㅤㅤ

Formula :

★ Sum of four exterior angle of quadrilateral = 360°

ㅤㅤ

Calculations :

→ 70 + 80 + 70 + x = 360

→ x + 220 = 360

ㅤㅤ

★ Now, sum of four exterior ange - 220°.

ㅤㅤ

→ x = 360 - 220

→ x = 140°

ㅤㅤ

Therefore, 140° is the value of x.
