given: < 2 ≅ < 4, m< 2=110° proof: m< 3 = 70° m∠2 = m∠4 definition of congruent angles m∠4 = 110º b. ∠3 and ∠4 are a linear pair definition of a linear pair (shown in diagram) ∠3 and ∠4 are supplementary linear pair postulate m∠3 + m∠4 = 180º c. m∠3 = 70º d.
Hell . what are the solutions to `10x^2 - 38x - 8 = 0`? is this when i find the factors and use the numbers within the factors to determine the zeros? i hope that made sense lol
