It would be 348
as A= lw+l((w
/2)^2+h^2)^0.5+w((l
/2)^2+h^2)^0.5
where l=12, w=12, h=6
A=347.65 ~ 348
Answer:
x = 33/3 = 11
Step-by-step explanation:
A and B are corresponding angles and are therefore equal.
Thus, A = 8x - 8 = B = 5x + 25, or
3x = 33
and so x = 33/3 = 11
Answer with explanation:
In Δ ABC and ΔD BC
∠A=∠D-------Given
∠ABC=∠DCB-------Each being 90° given in the Diagram.
Side, BC is Common.
⇒⇒Δ ABC ≅ ΔD BC-------[AAS]
When two triangles are congruent , their areas are equal.
So, Area(ABC)=Area (DCB)
Option B :⇒ A AS
Answer:
A) 5x-6y=3
B) 7y=2x+8
B) -2x + 7y = 8 then multiplying "B" by 2.5
B) -5x +17.5y = 20 then adding this to A
A) 5x -6y = 3
11.5y = 23
y = 2
x = 3
