Answer:
The acute angle would be 30 degrees.
Step-by-step explanation:
so for this equation, I would do 7/8 = 72/x
1 72
- = -
8 x
Cross multiply to get 72 * 8 = 1x
solve for X 576 = x
Answer:
1+1= 2.
Step-by-step explanation:
Have a good day!
Answer:
Step-by-step explanation:
A 2nd order polynomial such as this one will have 2 roots; a 3rd order polynomial 3 roots, and so on.
The quadratic formula is one of the faster ways (in this situation, at least) in which to find the roots. From 2x^2 + 4x + 7 we get a = 2, b = 4 and c = 7.
Then the discriminant is b^2 - 4ac, or, here, 4^2 - 4(2)(7), or -40. Because the discriminant is negative, we know that the roots will be complex and unequal.
Using the quadratic formula:
-4 ±√[-40] -4 ± 2i√10
x = ------------------ = ------------------
4 4
-2 ± i√10
Thus, the roots are x = ------------------
2
