Answer:
40 degrees
Step-by-step explanation:
-10+40=30
Answer: 
Step-by-step explanation:
Given: u and v be are the solutions of
Let
is the quadratic equation and u and v are the zeroes/solutions then
Sum of zeroes; 
Product of zeroes; 
Comparing
to
we get a= 3 , b= 5 and c = 7


Now we have to find
adding and subtracting 2uv in numerator we get

Substituting the values from (i) and (ii) we get

Hence, the value of
is 
Answer:
I used desmos and graphed it-
Hope this helps-
V= 4/3 • 3.14 • radius to the 3rd power.
If you don't have the radius, you can find it by dividing the diameter by 2.
Hope this helps!
