Answer:

Area = 3,656.6 m²

Step-by-step explanation:

Area enclosed by the track is composed of two semicircles and a rectangle.

Area = area of two semicircles + area of rectangle

= 2(½*πr²) + L*W

Where,

radius of semicircle (r) = ½of 40 m = 20 m

Length of rectangle (L) = 60 m

Width of rectangle (W) = 40 m

Plug in the values

Area = 2(½*π*20²) + 60*40

Area = 400π + 2,400

Area = 3,656.6 m² (aooroximated to nearest tenth)

leonid [27]

Answer:

Step-by-step explanation:

Sum of all angles of triangle = 180

39 + 102 + x = 180

         141 + x = 180

Subtract 141 from both sides

                 x = 180 - 141

I need it step by step​
elena-s [515]

Answer:

Step-by-step explanation:

we want y by itself...sooo

y - 19 = - \frac{6}{10}(x - (-5))

y - 19 = - \frac{6}{10}(x+5)

y - 19 =  - \frac{6}{10}x - \frac{6}{2}

y = - \frac{6}{10}x - 3 +19

y = - \frac{6}{10}x + 16
