Answer:
The Question is Incomplete still What i understood I let you Explain.
x = 78°
Step-by-step explanation:
Let
m∠ A = 78°
m∠ B = 56°
m∠ C = 100°
m∠ D = (x + 48)°
Be angles of Quadrilateral.
To Find:
x = ?
Solution:
Property of a Quadrilateral sum of the measures of the angle is 360°.
∴ m∠ A + m∠ B + m∠ C + m∠ D = 360°
Substituting above given values we get
∴ 78° +56° + 100° + ( x + 48° ) = 360°
∴ x + 282° = 360°
∴ x = 360° - 282°
∴ x = 78° ........... which the required answer
Answer:
B

it between B and c not really sure though
Answer:
D. x=4 only
Step-by-step explanation:
