I believe it’s 86
Since it tells you the measurements of two arcs that are opposite of one another you just add them together and divide it by two since the arcs correspond with the angle you’re looking for 86 is your answer
Answer:
a) 0
b) scalene and obtuse
Step-by-step explanation:
∠A = 20
∠B = 60
∠C = 180 - 20 - 60 = 100 (obtuse)
Since none of the angles are equal, no sides are equal either
So, it's a scalene triangle
Since one angle is obtuse, it's an obtuse triangle
I believe the equation would be y = -1/4x + 4
