see the attached figure with letters to better understand the problem
we know that
In the right triangle ABD

In the right triangle BCD

remember that
m< BAD=m<CBD
therefore

equate the equations

Answer: Pearl
Step-by-step explanation:
In step 2, she justified her step by the definition of vertical angles. However, angles AKL and GKB do not share a common side, meaning they are not adjacent angles.
Answer:
x = 12
Step-by-step explanation:
Solve for x:
360 - 30 x = 0
Subtract 360 from both sides:
(360 - 360) - 30 x = -360
360 - 360 = 0:
-30 x = -360
Divide both sides of -30 x = -360 by -30:
(-30 x)/(-30) = (-360)/(-30)
(-30)/(-30) = 1:
x = (-360)/(-30)
The gcd of 360 and -30 is 30, so (-360)/(-30) = (-(30×12))/(30 (-1)) = 30/30×(-12)/(-1) = (-12)/(-1):
x = (-12)/(-1)
(-12)/(-1) = (-1)/(-1)×12 = 12:
Answer: x = 12
