Answer:
x=63
Step-by-step explanation:
The two interior angles add up the the exterior angle, so 51+x+12=2x. From there, solve to get x=63. Hope this helped!
Yes. If the side lengths are different, you can end up with different angle measurements (example: SSA~ property. You can have two sides that are the same but you can make two different triangles with those side lengths and that one angle.)
Answer:
d = 25
Step-by-step explanation:

The value of d has to satisfy the inequality
so replace d with one of the given options

We have to simplify the fraction first
