Answer:
x = 100°
Step-by-step explanation:
The measure of a chord- chord angle is half the sum of the arcs intercepted by the angle and its vertical angle, that is
x =
(71 + 129)° = 0.5 × 200° = 100°
what is your question then?
(-7,1) is a solution to the inequality y<0.5x+9
Answer:8.5 is x but there is an extra 1
Step-by-step explanation:18x8.5=153+8=162 with an extra one is 162
Answer is 7.b because of the angles
