In a kite-string design, two threads cross. The four angles at the crossing are y, (y + 30), y, (y + 30) going around. Using the angle-sum around a point, find y.

Question

Accepted Answer

75. Sum around the point = 360°: y + (y + 30) + y + (y + 30) = 360, so 4y + 60 = 360, 4y = 300, y = 75°.

In a kite-string design, two threads cross. The four angles at the crossing are $y, (y + 30), y, (y + 30)$ going around. Using the angle-sum around a point, find $y$ .
