I think I would be 1 but I am not so sure
Step-by-step explanation:
All the sides of the triangle are equal
Therefore, it is a equilateral triangle
and all angles measure 60°.
So, 25x-15= 60
25x = 60+15= 75
x= 75/25
x= 3
2y = 60
y=30
optionA
Answer:

Step-by-step explanation:
The equation of a circle is:
, where x_1 is the x coordinate of the center, y_1 is the y coordinate of the center, and r is the radius.
In this case, x_1 = -8, y_1 = 14, and r = 4.3589. Plugging these into the equation, we get:

If you want, you can round 4.3589^2 to 19.
Then, the answer would be:
.
Hope this helps!
