Use what you know about sine, cosine, and tangent to calculate the height of the buildings in the diagram below.

x = 32 feet

Step-by-step explanation:

By applying tangent rule in ΔACD,

tan(40°) =

             =

             =

x + BC = 73 -----(1)

By applying tangent rule in ΔBCD,

tan(25°) =

             =

BC = 40.57

By substituting the value of BC in equation (1),

x + 40.57 = 73

x = 32.43

x ≈ 32 feet

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
