If isosceles triangle ABC has a 130° angle at vertex B, which statement must be true? Om ZA= 15° and mC = 35° OmZA+ m ZB = 155° OmZA+ m2C = 60° OmZA= 20° and mZC = 30°​

Me because some of question i don’t understand

How do i start to solve? would appreciate a walk-thru! a bird sitting 16ft above the ground in an apple tree dislodges an apple. after how many seconds does the apple land on the ground? (assuming that no branches will interfere with it's fall)

Find the quotient with the restriction.
