Answer:
d = 7.2
Step-by-step explanation:
We can cross multiply the equation to get:
6 * 30 = 25 * d
(* is multiplication sign by the way)
180 = 25d
Divide both sides by 25 to get:
d = 7.2
The measure of the angle is half the measure of the opposite arc.
.. ? = 78°/2 = 39°
4-2=2
6*2=12
2+12=14
14 is the answer
Two lines that intersect to create a 90 degree angle
