Answer:
5th choice) a , c , b
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°.
