Answer:

b = 60.26

Step-by-step explanation:

To comfortably solve for b, we employ the SINE RULE

SINE RULE:

sinA/a = sinB/b = sinC/c

Where a, b and c are the sides (length) of the triangle

Where A, B , and C are the ANGLES of the triangle.

Comparing angles to resolve for b, we have:

sinA/ a = sinB/b

sin46.7 / 44 = sin85.3 / b

Cross Multiply to solve for b, we have:

b * sin46.7 = 44 * sin85.3

b * 0.728 = 44 * 0.997

b = 43.868 / 0.728

b = 60.258

b = 60.26

Solve for x : 1/a+b+x =1/a+1/b+1/x
ANTONII [103]

Answer:

  x ∈ {-a, -b}

Step-by-step explanation:

  1/(a+b+x) = 1/a +1/b +1/x . . . . given

  abx = bx(a+b+x) +ax(a+b+x) +ab(a+b+x) . . . . multiply by abx(a+b+x)

  (a+b)x^2 +(a+b)^2x +ab(a+b) = 0 . . . . . subtract abx

  x^2 + (a+b)x +ab = 0 . . . . . divide by (a+b)

This is a quadratic equation in x. It will have two solutions, as given by the quadratic formula.

  x = (-(a+b) ±√((a+b)^2 -4(1)(ab))/(2(1)) = (-(a+b) ± |a -b|)/2

Without loss of generality, we can assume a ≥ b, so |a -b| ≥ 0. Then ...

  x = (-a -b -a +b)/2 = -a

  x = (-a -b +a -b)/2 = -b

There are two solutions: x ∈ {-a, -b}.

Determine the center and radius of the following circle equation: x^2+y^2+20x+8y+35=0
natta225 [31]

Answer:

center: (-10,-4)

radius: 9

Step-by-step explanation:

Let's start off by moving the 35 to the other side and grouping the x and y terms we have

(x²+20x)+(y²+8y)= -35

Next we take the term with the x coeficcent, divide it by 2, and square it

so

for the x we would do (20/2)²=100

and make sure we add that to the 35

(x²+20x+100)+(y²+8y+16)= -35+100+16

next factor everythign to get

(x+10)²+(y+4)²=81

therefore the center is (-10,-4)

and the radius is √81 or 9
