Here is the more clearer picture

angle FDA = 75 degrees

angle JAI = 75 degrees

Step-by-step explanation:

In ΔDCE,

angle D + angle C + angle E = 180(sum of the interior angles of a triangle is always 180 degrees)

angle D + 80 + 25 = 180

angle D + 105 = 180

angle D = 180 - 105

angle D (I. e angle CDE ) = 75 degrees

Now, angle CDE and angle FDA are vertically opposite angles, so,

angle CDE = angle FDA (vertically opposite angles are congruent to each other)

therefore, angle FDA = 75 degrees

Now, angle CDE and angle BAD are corresponding angles, so,

angle CDE = angle BAD ( corresponding angles are congruent to each other)

angle BAD = 75 degrees

Now, angle BAD and angle JAI are vertically opposite angles, so,

angle BAD = angle JAI (vertically opposite angles are congruent to each other)

therefore, angle JAI = 75 degrees

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
