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

Answer:
Area is 30 square inches.
Step-by-step explanation:
Given:
The wooden cutout of the lightning bolt consists of 2 right angled triangles with the legs being 10 inches and 3 inches.
The area of this lightning bolt will be equal to the sum of the areas of the two right angled triangles.
The area of a triangle of base 'b' and height 'h' is given as:
Here, . Plug in solve for area of one of the triangles.
Therefore, area of the right angled triangle is:
Now, the two right angled triangles are congruent. So, total area is twice the area of one of the triangle.
Therefore, total area of the lightning bolt is in².
