Find the area of the shape shown below.
3
3
7
And it’s not 63

Area = 31.5 (I think)

Step-by-step explanation:

Split into 3 parts:

Rectangle: 7 · 3 = 21

Triangle 1: 3 · 3.5= 10.5

10.5 ÷ 2 = 5.25

Triangles(they are the same): 5.25 · 2 = 10.5

Area: 10.5 + 21 = 31.5

Area = 31.5

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

probability for j is 1/4

while

a is 1/6
