Kryger [21]

Answer:

The answer to your question is 25 ft

Step-by-step explanation:

Data

height = 20 ft

leg = 15 ft

length of the line = ?

To solve this problem use the Pythagorean theorem.

Height = short leg = b

leg = long leg = a

length of the line = hypotenuse = c

- Substitution

c² = (20)² + (15)²

-Simplification

c² = 400 + 225

c² = 625

-Result

c = $\sqrt{625}$

c = 25 ft

Answer:

b = -152

Step-by-step explanation:

7 + 12 = 19
Plug 19 in: $\frac{b}{19} = -8$
Multiply each side by 19 to cancel out the 19 under b. It should now look like this: b = -152
