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
60% if there are only 10 white and black balls
Answer:
75 pounds
Step-by-step explanation:
(x) + (x) + (x+20) = 185
3x + 20 = 185
3x = 165
x = 55
Large dog = 55 + 20 = 75
From the statements given in the problem, we can say
that:
Final Score = (total of the remaining scores) * degree of
difficulty * 0.6
Therefore:
97.2 = (total of the remaining scores) * 4.0 * 0.6
total of the remaining scores = 40.5
Therefore the judges could have scored which has a total
of 40.5
