Question

Find the angle measure x in the figure: ∠90, ∠50, ∠110,∠ x

Answer 1

Step-by-step explanation:

we know that in a rectangle there are 4 sides and 4 angle

sum of all angle of a rectangle(quardilateral) is 360

90+50+110+x =360

250+x =360

x=360‐250

x=110

Answer 2

We know that sum of angles if a quadrilateral is 360°

Step-by-step explanation:

90° + 50° + 110° + x = 360°

250° + x = 360°

x = 360° - 250°

x = 110°
