Answer:
134
Step-by-step explanation:
Angle Formed by Two Chords= 1/2(SUM of Intercepted Arcs)
x = 1/2 ( m DH + m BC)
x = 1/2 (144+ 124)
x = 1/2 ( 268)
x = 134
k= 16
89-9=80
80/5=16
16=k
Just solve for x:
-13 = 9x - 4
9x = -9
x = - 1
25 is the length of x, using the 30-60-90 special triangle method
