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

Given f(x) is a linear function with slope 3 and y-intercept -5, what is the equation of f(x) in standard form?
lawyer [7]

The standard form:

Ax+By=C

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept

We have m = 3 and b = -5.

Substitute:

y=3x-5         subtract 3x from both sides

-3x+y=-5             change the signs

3x-y=5

What is 36 percent of 210?
ohaa [14]

Hey there!

Let's start by finding what 1% of 210 is.

This can be done by dividing 210 by 100, since 1% is the same as 1/100 of something.

210 ÷ 100 = 2.1

To find 36%, we can multiply 2.1 by 36.

2.1 x 36 = 75.6

So, 36% of 201 is 75.6.

Hope this helps!
