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)?
A) 413 ft
B)402 ft
C)387ft
D)300 ft

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

a) 0

step-by-step explanation:

i^413 x i^0 = 0 as any number multiplied by a zero is
