N(n-1)/2
for any integer n, n to the 3rd power > 0. (-2)^2 = -2 *-2=-8
each angle in a right triangle has a different measure.
both fractions reduce to 1/3
Area of the base = 6 (1/2 x 4.3 x 5) = 64.5cm
Area of the top = area of the base = 64.5cm
Area of the 6 side rectangles = 6 x 5 x 11 = 330 cm
Total surface area = 64.5 + 64. 5+ 330 = 459 cm²
------------------------------------------------------------------------
Answer: Total surface area = 459 cm²

Vertex: (5,0)
Focus: (5,1/4)
Axis of symmetry: x=5
Directrix: y= -1/4
The diagonal of a rhombus divides it into two congruent isosceles triangles.
So ∠CBD ≅ ∠CDB
∠CBD + ∠CDB + 68 = 180
2∠CBD = 180 - 68 = 112
∠CBD = 56
We also have
∠BDE + ∠E + ∠DBE = 180
∠DBE = 180 - 73 - 36 = 71
∠EBC = ∠EBD - ∠CBD = 71 - 56 = 15
Answer: ∠EBC = 15 degrees
