We will use Pythagorean Theorem:
HC^2=20^2-12^2=400-144=256
HC= $\sqrt{256}$ =16
HD^2=16^2-14^2=256-196=60
HD= $\sqrt{60}$ =7.7459
Answer: HD=7.7 in.

What is the answer for AC =

Triss [41]

Answer:

The length of AC is 2.33 units.

Step-by-step explanation:

You have to use Tangent Rule, tanθ = opposite/adjacent :

$\tan(θ) = \frac{oppo.}{adj.}$

Let oppo. = AC,

Let adj. = BC = 5,

Let θ = 25°,

$\tan(25) = \frac{ac}{5}$

$ac = 5 \tan(25)$

$ac = 2.33 \: units \: (near.hundredth)$

kirill [66]

The number of ways to select 4 digits from 10 digits is
₁₀C₄ = 10!/(4!*6!)
= (10*9*8*7*6!)/(4*3*2*1*6!)
= (10*9*8*7)/(4*3*2)
= 210

If order is not important, the number of arrangements of 6,7,8,9 in any order is
4! = 4*3*2*1
= 24
The probability that these 4 digits are assigned is
24/210 = 0.1143
