How many lines of symmetry does the figure have? If the figure has no line symmetry, enter the number
1 answer:
Answer:
One
Step-by-step explanation:
Line of symmetry of a figure is an imaginary line about which the figure can be divided into two equal halves.
In other words, a line passing the center of the figure about which we can fold the figure into two halves overlapping each other.
For the trapezoid given in the figure, line of symmetry will be a vertical line perpendicular to the parallel sides.
Therefore, The figure has 1 line of symmetry.

Answer:
From the photo above i interpreted the question and drew a triangle to make it easier to solve
Tan is used to solve the question as we were given opposite (as height of the cliff) and to find Adjacent ( the distance between the foot of the cliff to the boat)
Tan θ =Opp/Adj
Tan 22°=15/a
Cross Multiply
aTanθ=15°
Divide both sides by Tan 22
aTan22/Tan22 = 15/Tan 22
a = 15/Tan 22°
a = 37.13 m
Therefore the distance between the foot of the cliff to the boat is 37.13 metres
