∠1 =5x+20 and ∠4 = 14x - 160, find the measure of angle ∠5.

An angle that measures between 90 and 180° is called a(,

Ab based on the given diagram, if m_1 = 60° then m 2 = 30 60 90 180

(10. in the figure, a aabc is drawn tocircumscribe a circle of radius 3 cm ,such thatthe segments bd and dc are respectively oflength 6 cm and 9 cm. find the length ofsides ab and ac.
