In the diagram, AABC is isosceles, BC is extended to D, AB = AC, and mZA = 80.

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

i think asking google will you get the answer to that question

thus, the first answer choice, y = sec x, is the correct one
