Answer:
Step-by-step explanation:
Area of polygon = area of square + area of triangle
Square:
Side = 12 cm
Area of square = side *side
= 12 * 12
= 144 sq.cm
Triangle:
base (b) = 12 cm
Height h = 19 cm
= 6 * 19
= 114 sq.cm
Area of polygon = 144 + 114 = 258 square cm
Answer:
I believe it is a=64; b=2 divided by 10 (I'm sorry if it's wrong I hope you pass)
∠1 and ∠2 are RIGHT ANGLES, VERTICAL ANGLES, and SUPPLEMENTARY ANGLES.
Hope this helps!
