Answer:

The value of x° = 134°

Step-by-step explanation:

Given the angles of a quadrilateral

100°

51°

75°

We know that the sum of interior angles in a quadrilateral is 360°.

100° + 51° + 75° + x° = 360°

226° + x° = 360°

subtracting 226° from both sides

226° + x° - 226° = 360° - 226°

x° = 134°

Therefore, the value of x° = 134°

VERIFICATION:

100° + 51° + 75° + 134° = 360°

360°= 360°

16 years old.

Step-by-step explanation:

(24+24+15+16+19+X) / 6 = 19

(98 + X) / 6 = 19

98 + X = (19)*(6)

98 + X = 114

X = 114-98

X = 16
