proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.
step-by-step explanation:
an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
step-by-step explanation:
i found the life tables for the year 2012.
life table of males at age 30. probability of dying between ages x and x+1
total population:
29–30 . . . . . . . . . . . . 0.001030
30–31 . . . . . . . . . . . . 0.001061
males:
29–30 . . . . . . . . . . . . 0.001420
30–31 . . . . . . . . . . . . 0.001448
white population

jacob, non hispanic white male. 30 years old.
probability that jacob lives to be 30 years old.
since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.
probability of living to be 30 y.o.
29 - 30 : 1 - 0.001477 = 0.998523
30 - 31 : 1 - 0.001503 = 0.998497
i think the answer is d im not sure
