Answer:
a. m<A = 35°
b. m<CBD = 61°
c. m AD is sin55 = AD/40 AD = 32.77
d. m BC is sin 29 = 22.94/BC BC = 47.32
e. m CD is tan 29 = 22.94/CD CD = 41.38
f. m BD is cos 55 = BD/40 BD = 22.94

Step-by-step explanation:
each pound is 2 kilogram
Answer:
x=-9
Step-by-step explanation:

As the bases(3) are same,
we can conclude that the powers are equal.
Hence,

Christy dove to the depth of 12 feet below the surface = -12 feet
(Below sea level means to be below zero, which are negative numbers)
Christy dove 12 feet back up to the surface= +12 feet
( When we come back up to the surface, the distance is taken always positive)
Therefore, we have to find the overall change,
Overall change = -12 feet + 12 feet
= -12 feet + 12 feet
= 0 ft.
Therefore, overall change is 0 ft.
