The two triangles are similar.
The angles of a triangle sum to 180°. Using the known angles in the first triangle, we find the missing angle measure:
180-(65+70) = 180-135 = 45
We do the same for the second triangle:
180-(65+45) = 180 - 110 = 70
Any two triangles that have all 3 angles congruent is similar by AAA.
8(1+3) and that is that answer easy
So the which page that will have the 3 sticker, we must solve the least common multiple of 30, 50, 60. <span>A common multiple is a number that is a multiple of two or more numbers. The common multiples of 3 and 4 are 0, 12, 24, ....</span>
<span>The least common multiple (LCM) of two numbers is the smallest number (not zero) that is a multiple of both.</span>
<span>so the least common multiple of 30, 50 and 60 is 300. so the page that will have 3 stickers is 300th page</span>
