Quick Answer SSS
Proof
AC = DB
AB = DC
BC = BC This side is equal to itself and is common to both triangles.
Three sides of one triangle equal to 3 sides of the other means that the triangles are congruent. It is the Theorem you need.
Answer:
The height of the lighthouse is 
Step-by-step explanation:
Let
h -----> the height of the lighthouse
we know that
The tangent of angle of 68 degrees is equal to divide the height of the lighthouse by the horizontal distance from the buoy to the base of lighthouse
so

Solve for h

Answer:
If M<6=72
Step-by-step explanation:
Then What is M
M=72/6 =12
so M<7=12 by 7=84
therefoe M<7=84
Answer:
54 cm
Step-by-step explanation:
Measures are proportional on a scale drawing:
drawing measure : actual measure = 6 cm : 3 m = x : 27 m
The value on the right of the x ratio, 27, is 9 times 3, so the value of x will be 9 times 6 cm.
54 cm on the blueprint represents an actual distance of 27 meters.
Answer:
B
Step-by-step explanation:
The volume (V) of a triangular prism is
V = area of triangular end × length
area of Δ =
bh
where b is the base and h the perpendicular height
here b = 8 and h = 5, so
area = 0.5 × 8 × 5 = 20 units²
the length of the prism is 10, hence
V = 20 × 10 = 200 units³
