Find the size of angle C
(180° - 30°) : 2 = 75°
Find the size of angle B
(180° - 30°) : 2 = 75°
Find the size of angle X
Step 1] 180° - 123° = 57° ; [Step 2] Remember about isosceles triangle. ∠x =180° - 57° - 57° = 66°
Find the size of angle x
Step1] 180° - 154° = 26° ; [Step2] 180° - 73° = 107° ; [Step3] 180° - 26° -107° = 47° ; [Step4] ∠x = 180° - 47° = 133°
What is quadrilateral?
In geometry a quadrilateral is a four-sided polygon, having four edges (sides) and four corners (vertices).
