In a circle with a radius of 27 2/5 in., an arc is intercepted by a central angle of 7pi/4 radians an arc is intercepted by a central angle of 7x/4 what is the arc length

do your own work and don"t cheat.

step-by-step explanation:

96 39 cause 135 -96=39 im smart (i used a calculater)

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
