Answer:
- 140° is the measure of angle x.
Step-by-step explanation:
Given :
- Three angles in a quadrilateral respectively.
- ∠C = 70° ; ∠B = 80° ; ∠A = 70°
To find :
- ∠x
Solution :
- Sum of all the exterior angles in a quadrilateral is equal to 360°.
∠A + ∠B + ∠C + ∠D = 360°
⇒ 70° + 80° + 70° + x = 360°
⇒ 140° + 80° + x = 360°
⇒ 220° + x = 360°
∴ x = 140°
∴ The measure of x (∠D) is 140°.

Answer:
The value of x is 140°
Step-by-step explanation:
110+100+110+p=360°
p=360°-320°
p= 40°
angle x = 180°-40°
= 140°
