D because if you multiply y 8 times it will no longer be doubling the area
Answer:
41ft is your answer
left side=√(12²+12²)=16.97=17ft
perimeter=sum of all side=12+12+17=41ft
Answer:
∠ D = 28°
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ EBC is an exterior angle of Δ ABE, thus
∠ EBC = 90° + 34° = 124°
BD bisects ∠ EBC, so
∠ EBD = 124° ÷ 2 = 62° , then
∠ D = 180° - (90 + 62)° = 180° - 152° = 28° ( angle sum of triangle )
