Question

please help me to find angle x.​

Answer 1

Answer:

according to angle sum propert

Step-by-step explanation:

360° = 70 + 60 + x + 90 (b'cos it is perpendicular)

so,

220 + x = 360

x = 360 - 220

x = 140°

Answer 2

Answer:

∠x° = 140°

Step-by-step explanation:

here, it is a quadrilateral and we know that sum of all angles of quadrilateral is 360°.

so, ∠70°+∠60°+∠x°+∠90° = ∠360°

   = ∠x°+∠220° = ∠360°

   = ∠x° = ∠360°-∠220°

   = ∠x° = ∠140°

so, ∠x° = ∠140°

hope it help.
