there are six sides of a dice, numbered one through six. 5 and 6 are greater than four, so there is a 2/6 chance that you will roll a number greater than 4, or 1/3. multiply 72 times 1/3 and that equals 24. 24 out of the 72 (24/72 = 1/3)times is how much you could expect to get a number greater than 4.
Let x and y be the angles X= 3•y-8 X+ y = 180 Substitute first relationship in second 3y-8+y=180 4y=180+8 Y =188/4= 47 degrees X= 180-47=133 degrees The measure of the large angle is 133 degrees
