5. Find the length of AD.
Given : angle ABC = 60°,
angle DBC = 45°



and
BC = 40 cm.
40 cm​

Answer 1

Answer:

AD= 29.28 cm

Step-by-step explanation:

BC = 40 cm

∠ DBC = 45°

∠ ABC = 60

IN triangle ABC

tan 60 =AC / 40

√3=AC / 40

AC= 40√3

AC=69.2820 cm

In triangle BCD

tan 45 =DC / 40

1 = DC /40

DC= 40 cm

AD= AC-DC

AD =69.28 -40

AD= 29.28 cm
