Answer:
which c?
Step-by-step explanation:
Step-by-step explanation:
an object and its shadow create a right-angled triangle.
2 objects and their shadows create 2 similar right-angled triangles.
that means the angles are the same, and the side lengths of one triangle all correlate with the corresponding side lengths of the other triangle via the same factor.
so,
42 × f = 6
f = 6/42 = 1/7
the length of Joel's shadow is then
20 × f = 20 × 1/7 = 2.857142857... ft
Answer:8 ft
Step-by-step explanation:base is equal to 8ft and the area is 64ft so
Area of parallelograms =base×height
64=8×height
64÷8=HEIGHT
8
