Answer:

9.9

Step-by-step explanation:

We know each leg is 7 and the square of both of these will equal the square of the hypotenuse:

7^2=49\\49\times2=98\\\sqrt[2]{98}=9.9

It is 45 yd from the base of the pole.

The pieces of the right triangle we are given are one of the legs (the height of the pole, 60 yd) and the hypotenuse (the length of the cable, 75 yd).  Using the Pythagorean theorem, we have:

60²+b²=75²
3600+b²=5625

Subtract 3600 from both sides:
3600+b²-3600=5625-3600
b²=2025

Take the square root of both sides:
√(b²) = √2025
b = 45

What is the sum (2/5x + 5/8) + (1/5x - 1/4)? a. 3/5 x + 1/8 b. 3/5 x + 3/8 c. 3/5x + 5/8 d. 3/5x + 7/8​
ozzi

Answer:

3/5x + 3/8

Step-by-step explanation:

2/5x + 5/8 + 1/5x - 1/4

1. Combine like terms so now u have

3/5x + <u><em>3/8 </em></u>

In case you want to know how I got 3/8

You want a common denominator so

from  5/8 + 1/4, make both denominator 8

so 1 *2/ 4* 2

so now you converted the 1/4 to 2/8

So then 5/8 - 2/8 gives u 3/8 and that's how i got 3/8

Hope this helped!
