Notes: Finding x and y. Step 2. Now there is enough information to find y. y+25=90 y=65 Step 3: Find x If this angle is 90, Look at the green triangle. so is this one. Now that we know y = 65, we can find. 65 + 20 + = 180 = 95 Step 1. Look for a triangle that has enough information to solve. Sometimes you have to ignore a line. Look at the highlighted triangle. Step 4: = 95. x + 95 make a linear pair. +x = 180 95 + x =180 x = 85
Practice Classify the triangles: 1. By sides 2. By angles.
