Luke plays an online game and takes a total of 74.7 seconds to complete two rounds. if he took 14.6 seconds to clear round two how much time did he take it finsh one round?

60.1 seconds

Step-by-step explanation:

total time = round 1 + round 2

74.7 = x + 14.6

x = 74.7 - 14.6

x = 60.1 seconds

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

sine
