How can you know if this equation is true? 1/2+3/8=4/10=2/5
A. Because 1 + 3 = 4 and 2 + 8 = 10, this equation must be true,
B. Because } 2/5 < 1/2 , this equation can not be true.

C. This equation must be true, because when you add fractions the sum is always less than 1/2

D. Because 3/8 <1/2 this equation must be true.

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

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3
