The tickmarks tell us that WX and XY are the congruent sides, ie they are the same length. This means we have an isosceles triangle. The angles opposite the congruent sides are congruent angles.
angle W = angle Y = 35
From here, we use the idea that for any triangle the angles must always add to 180
The total number is 12 (assuming the dice would be rolled 12 times) 7 is a number in the range and it will appear once in the 12 rolls because each number shows each time. 1 (how many times 7 will show)/ 12(total number of rolls)
The answer is work: 208/2 = 114 now this is easier. the answer is 62, as 62 is 10 more than 52, so once added,(obviously) that gets you 114, and the width is 52.
