    BC = 25 / (tan 45) and CD = 25 / (tan 30)

    BD = BC + CD

    BD = (25 / (tan 45)) + (25 / (tan 30))

    BD = 25 + 43.30

    BD = 68.30

    The ratios of the lengths of the sides of 45-45-90 and 30-60-90 triangles are _____________. Use those ratios to determine the length of BD. No "Top Mathematics Answerers" are going to do your homework for you, so you are just going to have to look up those values yourself, or wait for someone who is not a "Top Mathematics Answerer" to give you the answer.
