Answer:

x=16

Step-by-step explanation:

Because this is an isosceles triangle the angle 2x+3 is the same as the missing angle. The angles in triangles add up to 180 degrees. 180-110=70.

Because the two angles are the same you can divide 70 by 2 to get 35.

35=2x+3.

35-3=2x+3-3

32=2x

32/2=2x/2

16=x

Since the triangle is an isosceles triangle, it’s base angles are equal which means two angles are 2x+3 and other angle is 110
Then
2x+3+2x+3+110=180(sum of angles of triangle)
4x+6=180-110
4x+6=70
4x=70-6
4x=64
x=64/4
x=16

Express f(x) =3\x²- 1 in partial fraction

BARSIC [14]

3/(x ² - 1) = 3/((x - 1) (x + 1)) = a/(x - 1) + b/(x + 1)

==> 3 = a (x + 1) + b (x - 1)

==> 3 = (a + b) x + a - b

==> a + b = 3 and a - b = 0

==> a = b

==> a + b = 2a = 3 ==> a = 2/3 and b = 2/3

So you have

3/(x ² - 1) = 2/(3(x - 1)) + 2/(3(x + 1))
