Calculate angles X & Y.
X=35°+38°=73°
y=73°+50°=123°

BLUE AREA = ???
Blue area = 1/2 area of the Square = 1/2 × 8^2 = 32 u^2
--------
Task find the area in blue
By observation the blue area is in in fact
½ of the square each side at 8 cms.
Area in blue = ½(8 × 8} = ½*64 = 32cm²
---------------------
2! – 3! + 4! – 5! + 6! =
= 2 – 6 + 24 – 120 + 720
= 620
-------------------
Using the provided information find 𝑥
50° + (40° + 𝑥) + (180° – 120°) = 180°
50° + 40° + 𝑥 + 60° = 180°
𝑥 + 150° = 180°
𝑥 = 180° – 150°
∴ 𝑥 = 30°
