5th choice) a , c , b

Step-by-step explanation:

Find the last angle measurement. Note that the total angle measurement of the interior angles of a triangle = 180°.

It is given that two of them are 50 & 60. Find the last measurement:

180 - (50 + 60) = 180 - 110 = 70.

Note that to find the sides without proper measurements, the angles OPPOSITE of the sides determine the value. The greater the angle's value, the greater the opposite side's measurement value.

In this case, side a will be the least as it is opposite of 50°, side c will be next as it is opposite of 60°, and side b will be the greatest as it is opposite of 70°.

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
