Given that measure of angle 6 is 1/8 of measure of angle 4. find the measures of these two angles if a∥b . statement reason 1. a∥b given 2. m∠6= 1 8 m∠ given 3. m∠6+m∠4 = 4. m∠6+8m∠ = 180° substitution 6. m∠6 = m∠4= algebra

△cde maps to △stu with the transformations (x, y) arrowright (x − 2, y − 2) arrowright (3x, 3y) arrowright (x, −y). if cd = a + 1, de = 2a − 1, st = 2b + 3 and tu = b + 6, find the values of a and b. the value of a is and the value of b is .
