anonymous · Answer

bro ans will be 100 out of four question but how...

ajprincess · Answer

Assuming that they are angles
x+y=180
4x=5y
y=4x/5
x+4x/5=180
(5x+4x)/5=180
9x=180*5
9x=900
nw solve for x.:)

A horse is tied at the corner of a rectangular field, whose length is 20m and width is 16m with a rope whose length is 14 m. find the area which the horse can graze.

ajprincess · Answer

r there answer choices?

anonymous · Answer

154 sq. m. is ans but how?

anonymous · Answer

ok do.

ajprincess · Answer

since the horse is tied to a fixed point with the rope of length 14m the locus of it will be a circle with the radius 14m. the area it will cover within the field will be 1/4 of the area of the circle.
area the horse grazes=pi*r^2/4
                                =(22/7)*(14*14)*(1/4)
