A set of points that form a line are called a linear pattern
Both of the other angles are 40° because a triangle has a total angle of 180° and an isosceles triangle means that at least two of the sides have to be the same length (two angles must be the same)
180 - 100= 80
80 ÷ 2 = 40
Here is the solutions for 3-11
500 inches is greater than 40 feet because, every 12 inches is 1 foot. Since every 12 inches is 1 foot you have to divide. 500÷12=41.6667. Hope this helps!
