In the triangle bca, segment bc is congruent to segment ac. if the measure of angle b is 43 degrees what is the measure of angle a

M∠aoc is a straight angle angle boc = 6x + 29 m∠boc=6x+29 angle aob = 3x + 124 m∠aob=3x+124 ∘ find angle boc

Astandard deck of cards contains 52 cards. one card is selected from the deck. (a) compute the probability of randomly selecting a seven or king. (b) compute the probability of randomly selecting a seven or king or jack. (c) compute the probability of randomly selecting a queen or spade.

Consider the proof. given: segment ab is parallel to line de. prove: what is the missing statement in step 5?
