Given: △ABC with side lengths a, b, and c, and height h

Pavel [41]

Answer with explanation:

Given: In △ABC with side lengths a, b, and c, and height h, a vertical line extends from angle B perpendicular to side b.

To prove:→ Area(ΔABC)

$=\frac{1}{2}\times ab \sin C$

Proof:

In △ABC with side lengths a, b, and c, and height h ,

Area of ΔABC

$=\frac{1}{2}\times {\text{Base} \times {\text{height}$

Let perpendicular from angle , B on the side AC cuts AC at M.

Definition of sine

$\sin {\text{theta}}=\frac{\text{Perpendicular}}{\text{Hypotenuse}}\\\\\sin C=\frac{BM}{BC}\\\\ \sin C=\frac{h}{a}\\\\h=a\sin C$

Area of Triangle ΔABC

$=\frac{1}{2}\times b \times h\\\\=\frac{1}{2}\times b \times a \times \sin C$

-----Using Substitution Property,that is , h=a sin C

→Area = 1/2 b h

Inspecting Restaurants How many different ways can a city health department inspector visit restaurants in a city with restauran

tankabanditka [31]

Answer:

252 ways

Step-by-step explanation:

The missing details are:

$n = 10$ --- total restaurants

$r = 5$ --- restaurants to visit

Required

The number of ways to perform the visitation

The question is an illustration of combination;

So, we have:

$^nC_r = \frac{n!}{(n - r)!r!}$

This gives:

$^{10}C_5 = \frac{10!}{(10 - 5)!*5!}$

$^{10}C_5 = \frac{10!}{5!*5!}$

Expand

$^{10}C_5 = \frac{10*9*8*7*6*5!}{5!*5*4*3*2*1}$

Cancel out 5!

$^{10}C_5 = \frac{10*9*8*7*6}{5*4*3*2*1}$

$^{10}C_5 = \frac{30240}{120}$

$^{10}C_5 = 252$
