Two lengths of a triangle are shown.
Solnce55 [7]

Answer:

11 ft

Step-by-step explanation:

Given the two lengths of a triangle as

AB = 6ft

AC = 6ft

This is an isosceles triangle because only 2 sides are equal.

In an isosceles triangle, the sum of 2 (sides) lengths must be greater than the other length.

Therefore, let's assume the following:

i) AC + AB > BC

6 + 6 > BC

12 > BC (BC is less than 12)

BC < 12

ii) BC + AC > AB

BC + 6 > 6

BC > 6 - 6

BC > 0

Therefore the range of values for BC =

0 < BC < 12

Since BC must be bigger than one of the lengths and it must also be less than the sum of the 2 sides. The length of BC could be 11 because it is less than (6+6) 12 and greater than 6.

Solve the equation a = m – n for the variable n.
MaRussiya [10]

Answer:

m - a = n

Step-by-step explanation:

<u>Step 1:  Subtract m from both sides </u>

a - m = m - n - m

a - m = -n

<u>Step 2:  Divide both sides by -1 </u>

(a - m) / -1 = -n / -1

-a + m = n

m - a = n

Answer:  m - a = n

A building has a shadow that is 25 feet long. A person 6 feet tall cast a similar shadow. How long is the person's shadow?
mario62 [17]
Imagine the side of the building is one side to a triangle and the second would be from the top of the building to the point where the shadow ends and the third is from the base of the building to the point where the shadow ends. Just use the pythagoreon theorem to find stuff. I can't solve the problem you gave because you would need the height of the building
