Answer:
b = 230 degrees a= 25 degrees
Step-by-step explanation:
d and e are right angles (90 degrees) because when tangent meets radius at circumference a right angle is formed.
c= 180 - 65 - 90 = 25 degrees because angles in a triangle add up to 180
both triangles are congruent as they share the middle line, they have tangents that meet radi(which are equal), and both have right angles. this means that all angles are same in the triangles so a =c =25 and f=65.
65+65=130
360-130 = 230
because angles around a point add up to 360.
b=230
Answer:
C. 39
Step-by-step explanation:
m∠3 ≅ m∠5
4x - 7 = 6x - 81
-7 = 2x - 81
74 = 2x
37 = x
m∠5 = 6(37) - 81 = 141
m∠8 = 180 - 141 = 39
