Correct answer is : Area of triangle is $15\sqrt{3} sq.units$

Solution:-

We can do it in 2 methods.

Method 1:-

Given that AB=6, BC=10 and m∠B = 120

Then area of triangle = $\frac{1}{2}XbaseXheight$

Let us assume AB is base and D is an altitude from C onto AB.

Then sin(60)= $\frac{CD}{BC}$

CD = BC sin(60)

Hence height = $10*\frac{\sqrt{3}}{2}$ = $5\sqrt{3}$

Hence area of ΔABC = $\frac{1}{2} X6X5\sqrt{3} = 15\sqrt{3}$ sq.units

Method2:-

Area of triangle = $\frac{1}{2} acsin(B)$

Here a= BC=10, c=AB=6.

Hence area of triangle = $\frac{1}{2}X6X10sin(120) = 15\sqrt{3}$ sq.units

How do u simplify -1+- sqrt -24

MaRussiya [10]

First find the square root of -24 which would be -4.898979486 then either subtract 1 or add negative 1, it's the same thing, and that would give you -5.898979486.

14(0.89)^x+4.5 =162

lisabon 2012 [21]

$14(0.89)^{x + 4.5} = 162$
$\frac{14(0.89)^{x + 4.5}}{14} = \frac{162}{14}$
$0.89^{x + 4.5} = 11\frac{4}{7}$
$ln(0.89^{x + 4.5}) = ln(11\frac{4}{7})$
$(x + 4.5)ln(0.89) = ln(11\frac{4}{7})$
$\frac{(x + 4.5)ln(0.89)}{ln(0.89)} = \frac{ln(11\frac{4}{7})}{ln(0.89)}$
$x + 4.5 = -2101.14032500$
$x = 2105.64032500$
