The large triangle is an isosceles since both angles at the base each equal 42°.
In an isosceles triangle the altitude z is at the same time median , then it bisects the opposite side in the middle . So w = 120/2 = 60
Now let's calculate z:
tan 42° = (opposite side) / (adjacent side) = z/60
tan 42° = 0.9,
0.9 = z/60 and z = 54

Using scientific notation, the correct statement is given by:
C. Corporation C owns the most land. Corporation A owns 8 times more land than corporation B.
<h3>What is scientific notation?</h3>
A number in scientific notation is given by:

With the base being
.
Considering the amounts in scientific notation, the standard amounts in acres of each corporation are given as follows:
- Corporation A:
.
- Corporation B:
.
- Corporation C:
.
Hence corporation C owns the most land. 320,000/40,000 = 8, hence Corporation A owns 8 times more land than corporation B, and statement C is correct.
