  2. 9-1 The Tangent Ratio

  3. B c a C b A tan A =opposite side adjacent side tan A = a b

  4. B EX. Write the tangent ratio for A and B. tan A = tan B= √65 4 C A 7

  5. Before starting this problem change your calculator mode to degrees EX 2. Find the value of w to the nearest tenth tan = 3.9 ≈ w CROSS MULTIPLY w 6 28° w 1 (6)tan28°=w 28° 6

  6. Before starting this problem change your calculator mode to degrees OYO. Find the value of w to the nearest tenth tan = 12.4 ≈ w CROSS MULTIPLY w 9 54° w 1 (9)tan54°=w 9 54°

  7. Before starting this problem change your calculator mode to degrees EX 3. Find the value of w to the nearest tenth tan = w ≈ 5.1 CROSS MULTIPLY 67° 12 w 12 1 tan67°(w)= 12 tan67° tan67° 67° w

  8. Before starting this problem change your calculator mode to degrees OYO. Find the value of w to the nearest tenth tan = w ≈ 9 CROSS MULTIPLY 48° 10 w 10 1 tan48°(w)= 10 tan48° tan48° w 48°

  9. EX. 4 Using the inverse of tangent Find m X to the nearest degree. tan X = = m X = tan-1(1.5) m X ≈ 56° N 12 8 1.5 12 R X 8

  10. OYO….Using the inverse of tangent Find m N to the nearest degree. tan N = = m N = tan-1(0.875) m N ≈ 41° N 14 16 1.5 16 R X 14

  11. Geometry B Bellwork 2)Find the value of w to the nearest tenth tan = 7.8 ≈ w CROSS MULTIPLY w 13 31° w 1 (13)tan31°=w 31° 13

  12. Geometry B Bellwork 3) Using the inverse of tangent Find m N to the nearest degree. tan N = = m N = tan-1(0.6) m N ≈ 31° N 18 30 1.5 30 R X 18
