Question

р “The
measure of three angles of a quadrilateral
30, 70 and 100 find out the
measurement of fourth angle.​

Answer 1

Answer:

160

Step-by-step explanation:

We know measure of all angles of quadrilaterals = 360

Three angles are already given

Let fourth angle be =x

Therefore

30+70+100+x = 360

200+x = 360

X =360-200

X = 160

Fourth angle = 160

Answer 2

Answer:

Step-by-step explanation:

sum of the angles of a quadrilatarel = 360°

∠1 = 30°

∠2 = 70°

∠3 = 100°

∠4 = ?

so : ∠1  + ∠2 + ∠3 + ∠4 = 360°

30° + 70° + 100° + ∠4 = 360°

200° + ∠4 = 360°

∠4 = 360° - 200°

∠4 = 160°

SO THE MEASURE OF THE FOURTH ANGLE IS 160°
