No, they are complementary 30 in² Complement = 6°, Supplement = 96° Area of a rectangle = length x width Multiple answers for the reasons. Some Area of a parallelogram = base x height examples: The base and height always form a right angle = 40° since it's vertical to a 40° angle and ∠2 vertical angles are congruent 11 cm = 140° since it's the supplement of 28 cm² ∠3 ∠2 81 m² = 140° since it's vertical to or ∠1 ∠3 supplement of the 40° angle 50 in² 91 m² Multiple answers for the reasons.

No, they are complementary Complement = 6°, Supplement = 96° Multiple answers for the reasons. Some examples: ∠2 = 40° since it's vertical to a 40° angle and vertical angles are congruent ∠3 = 140° since it's the supplement of ∠2 ∠1 = 140° since it's vertical to ∠3 or supplement of the 40° angle Multiple answers for the reasons. Some examples: ∠1 = 68° since it's an alternate exterior angle to ∠5 ∠2 = 112° since it's supplemental to ∠1 ∠3 = 68° since it's vertical to ∠5 or corresponds to ∠1 ∠4 = 112° since it's supplemental to ∠3 and ∠5 ∠6 = 112° since it's supplemental to ∠5 or vertical to ∠4 or an alternate interior angle to ∠2 ∠7 = 68° since it's vertical to ∠1 or an alternate interior angle to ∠3 ∠8 = 112° since it's vertical to ∠2 or an alternate exterior angle to ∠4 10 m 16 ft 16 in 24 m 31.4 cm 14.444m 25.12 m 77.244 cm 15 m m cm m cm 42 cm 100 m 18 ft 64 m 21.98 m 200.96 in 100.48 in 25.12 ft 2.1 cm m in. m ft 24 cm² 121 m² 84 in² 108 m² 80 cm² 30 in² Area of a rectangle = length x width Area of a parallelogram = base x height The base and height always form a right angle 11 cm 28 cm² 81 m² 50 in² 91 m² 143 cm² 102 m² Area of a rectangle = length x width Area of a parallelogram = base x height The base and height always form a right angle 9 cm 60 ft² 78 m² 30 in² 84 in² 195 m² 5 in 90 ft² 91 m² 56 in² 105 in² 135 m² 10 in 314 m² 379.94 in² 78.5 m² 153.86 cm² 200.96 yd² Area of a circle = π x radius² cm2 in2 m2 cm2 yd2 254.34 m² 254.34 in² 50.24 m² 78.5 in² 153.86 m² Divide the diameter by 2 to find the radius.
