The proofing of the triangle is illustrated below.

<h3>How to illustrate the proof?</h3>

AB = c

BC = a

AC = b

h² = b² - x²

h² = a² - y²

a² - y² = b² - x²

a² = b² - x² + y²

Note that x = c - (c - x) = c

a² = b² - (-x)² + y²

a² = b² + c² + y²

Cos A = x/b

cos = adjacent/hypothenuse

x = bcosA

a² = b² + c² - 2bx

a² = b2 + c² - 2bccosA

Please help me please pleaee

Hello,

A.i. the circumference of a circle is nothing else but its perimeter which formula is π × diameter = π × 2 × radius

Let π = 22/7 ≈ 3.142857, the egyptian approximation

Then if C is the circumference of the circle i., C = 22/7 × 21 = (22 × 21) / 7 = (22× 7×3 )/7 = 22 ×3 = 66 cm

ii. Applying the same formula for the second circle gives us C = 22/7 × 8 = 176/7 ≈ 25.14 meters, rounded to the nearest hundredth...

Good luck !

During a store's opening month, they sold 925 DVD's and 507 Blu-ray discs. Each month thereafter, the number of DVD's sold per m
andreyandreev [35.5K]

The system of equations representing the number of Blue-ray discs and DVD's after t months are:

507 + 26t

925 - 12t

Each month, the number of DVD's sold decreases by 12, this can be modelled as:

number of DVD in opening month - (monthly decrease x number of months)

Number of DVD's in t months = 925 - 12t

Each month, the number of Blue-ray discs sold increases by 26, this can be modelled as:

number of blue-ray discs in opening month + (monthly increase x number of months)

Number of Blue-ray discs in t months = 507 + 26t
