Find the area of the figure. Round to the nearest tenth if necessary.
Ulleksa [173]

9514 1404 393

Answer:

  A.  12.28 km²

Step-by-step explanation:

The area of the figure is the sum of the areas of its parts. The area of the triangular part is ...

  A = 1/2bh

  A = 1/2(3 km)(4 km) = 6 km²

__

The area of the semicircular part is ...

  A = 1/2πr²

  A = 1/2(3.14)(2 km)² = 6.28 km²

__

Then the area of the figure is ...

  6 km² + 6.28 km² = 12.28 km²

Y+4=-2(x-1) slope intercept form
lys-0071 [83]
To convert this equation into slope intercept form simply distribute the number of -2 and put it in

Y = mx + b form

Y + 4 = -2(X-1)
Y + 4 = -2x + 2
Y = -2X + 2 - 4

Y = -2X - 2

I believe this is the solution in slope intercept form.

Find x for the trapezoid.<br> J<br> K<br> (2x+15).. (3x-20).<br> (x +15).<br> N4<br> M.
Harman [31]

Answer:

50°

Step-by-step explanation:

All quadrilaterals' interior angles sum to 360°:

(x + 15)° + (2x + 15)° + (3x - 20)° + x° = 360°

x + 15 + 2x + 15 + 3x - 20 + x = 360

7x + 10 = 360

7x = 360 - 10

7x = 350

x = 50°
