Which equation can be used to find the answer?

dania marks off 18.7 m of a playing field for a sports festival. she needs to mark off a total of 29 m to finish the field. how many more meters does dania have left to mark off?

a.
f = 29 ÷ 2
f = 14.5
14.5 m

b.
f – 18.7 = 29
f = 47.7
47.7 m

c.
f = 18.7 · 2
f = 37.4
37.4 m

d.
f + 18.7 = 29
f = 10.3
10.3 m

step-by-step explanation:

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

a. is correct
