Answer:
C
Step-by-step explanation:
I didn't use your formula bc I do not understand it =). I just did 975 divided by 780. When you do this you will get 125. This means that 975 is 125% of 780. So it has to be 25% more than 780. You can see that 780 divided by 4 (25 times 4 is 100 so 25 % is one fourth) is 195. Then 780 plus 195 is 975.
Hope this helped you!

Answer:
x=45
y=30
Step-by-step explanation:
We know that there are two isosceles triangles which means two of the angles in the triangle are equivalent. We can use this to first solve for x
180-90=2x (This is for the smaller triangle)
90=2x
x=45
Now we find the measure of the angle in the bigger triangle.
(180-30)/2=150/2=75
Since y+x=75
y=75-x
y=75-45
y=30
I got 6.49204 but you will need to round so D 6.5
I added all of the numbers up
