Question

Help please urgent hmwk

Answer 1

ab^2 = be^2 + ae^2

6.5^2 = 6^2 + ae^2

42.25 = 36 +ae^2

6.25 = ae^2

2.5 = ae

23 = ae +ef +fd

23 = 2.5 + 9 +fd

fd = 11.5

tan D = opp/adj

tan D= cf /fd

tan  D = 6/11.5

D = tan^-1 (6/11.5)

D =27.5528

D = 27.6 degrees

Answer 2

ab^2 = be^2 + ae^2  pythagorean theorem  e is the point below b

6.5^2 = 6^2 + ae^2

42.25 = 36 +ae^2

6.25 = ae^2

2.5 = ae

23 = ae +ef +fd                                 f is the point below c

23 = 2.5 + 9 +fd

fd = 11.5

tan D = opp/adj

tan D= cf /fd

tan  D = 6/11.5

D = tan^-1 (6/11.5)

D =27.5528

D = 27.6 degrees
