Archaeologists have recently started uncovering remains of James Fort in Virginia. The fort was in the shape of an isosceles triangle. Unfortunately, one corner has disappeared into the James River. If the remaining complete wall measures 300 feet and
the remaining corners measure 46.50 and 87°, how long was the larger incomplete wall (side AC)?

step-by-step explanation:

first, eliminate the parenthesis:

x

+

2

−

4

x

second, group like terms:

3

−

4

x

+

2

third, combine like terms:

a - base

b - exponent

so,

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
