Answer: 45
Step-by-step explanation:
By the tangent secant theorem we have AB^2 = BD(BD + CD)
So...
14^2 = 4(CD +4)
196 = 4CD + 16
4CD = 180
CD = 45
Answer:
b
Step-by-step explanation:
can i have brainlyest
:D
A is supplementary to the 35 degree angle; therefore ...
a= 145.
b is vertical to the 35 degree angle, so ...
b = 35.
c is vertical to a, so ...
c = 35.
d is a corresponding angle to a, so ...
d = 145.
e corresponds to the given 35 degree angle, so ...
e = 35.
Finally g corresponds with b, and f corresponds with c, so ...
g =35,
f = 35.
