Geometry CP 8.4 Day 2 Worksheet Name: Key #1-5, ABCD is a rhombus. One angle of ABCD is 73°, find the other three angles. 73°, 107°, 107° The ratio of m∠A to m∠B is 13:5. Find m∠C. 13x + 5x = 180 18x = 180 x = 10 m∠C = 13(10) = 130° m∠A = 70°, find m∠DBC. m∠DBC = 55° F and E are the midpoints of AB and BC respectively. What type of triangle is FBE? Isosceles m∠ADC = 120° and AB = 10. Find the perimeter of ABCD. P = 10 + 10 + 5 + 5 = 30 In #6-7, ABCD is a rectangle. If AC = 3x + 6 and BD = 6x - 12, find AC. AC = BD 3x + 6 = 6x - 12 18 = 3x x = 6 AC = 3(6) + 6 = 24 If the diagonals intersect at E and DE = 8, find AC. AC = 16 8. Given parallelogram KMOP, m∠K = x + 3y, m∠O = x - 4, m∠P = 4y - 8. Find m∠K. x + 3y + x - 4 = 180 2x + 3y = 184 5y = 200 y = 40 x = 32 m∠K = x + 3y = 32 + 3(40) = 152° 9. Given parallelogram WSTV, WS = x + 5, WV = x + 9, VT = 2x + 1. Find the perimeter of WSTV. x + 5 = 2x + 1 4 = x P = 13 + 13 + 9 + 9 = 44 10. Given parallelogram ABCD, m∠A = 4x and m∠D = 3x - 4. Find m∠D and m∠C. x + 3x - 4 = 180 4x = 184 x = 46 m∠D = 3(46) - 4 = 134° m∠C = 180 - 134 = 46° The diagonals of rhombus WXYZ intersect at V. Given m∠XVY = 34° and WV = 7, find the indicated measure. m∠WVZ = 34° m∠WYZ = 112° WY = 7 + 7 = 14 XY = 12.5 The diagonals of rectangle PQRS intersect at T. Given that m∠RPS = 62° and QS = 18, find the indicated measure. m∠QPR = 90 - 62 = 28° m∠PTQ = 180 - 28 - 28 = 124° ST = 9 QR = 8.5 The diagonals of square EFGH intersect at J. Given that GJ = 15, find the indicated measure. m∠EJF = 90° m∠JFG = 45° FH = 15 + 15 = 30 EF (exact value) = 15√2
