π΄ = 12 πβ
Proof
Reference to the β± ABCD in the figure
1
Area of the β± ABCD= πππ π Γ πππ‘ππ‘π’ππ
Area of the β± ABCD= (π·πΆ) Γ (π΄πΏ)
Let π·πΆ = π ,π΄πΏ = β βΉ
Area of the β± ABCD= (π)(β)
Area of the β± ABCD= πβ
Area of the β³ADC= 12 πβ
Area, A, of circle of radius r
...
π΄ = 2ππβ

Reference to the triangle
8
Let altitude= π΄π·
Also in the right angle triangle ADC
π΄π·
π΄πΆ
= sin πΆ βΉ π΄π· = π΄πΆ sin πΆ
Since π΄πΆ = π βΉ π΄π· = π sin πΆ
Also in the right triangle ABD
π΄π·
π΄π΅
= sin π΅
Since π΄π΅ = π βΉ
π΄π·
π
= sin π΅ βΉ π΄π· = π sin π΅
Since
π΄π· = π sin π΅ and π΄π· = π sin πΆ
βΉ π sin π΅ = π sin πΆ βΉ
π
sin πΆ
=
π
sin π΅
Similarly from the same triangle ABC, drawing BEβ AC
9
In the right triangle AEB
π΅πΈ
π΄π΅
=
π΅πΈ
π
= sin π΄ βΉ π΅πΈ = π sin π΄
Similarly
In the right triangle BEC
π΅πΈ
π΅πΆ
= sin πΆ
Since π΅πΆ = π βΉ
π΅πΈ
π
= sin πΆ βΉ π΅πΈ = π sin πΆ
Now
10
π΅πΈ = π sin π΄ and π΅πΈ = π sin πΆ βΉ π sin π΄ = π sin πΆ
Or
π
sin πΆ
=
π
sin π΄
Combining the results
π
sin π΄
=
π
sin π΅
=
π
sin π΅
=
π
sin πΆ
and
π
sin πΆ
=
π
sin π΄
π
sin πΆ
Drawing BEβ to AC in the same triangle ABC
In the right angled triangle AEB
cos π΄ =
π΄πΈ
π΄π΅
=
π΄πΈ
π
βΉ π΄πΈ = π cos π΄
Also
11
we have:
(π΅πΈ)2 + (π΄πΈ)2 = (π΄π΅)2 Or
(π΅πΈ)2 = (π΄π΅)2 β (π΄πΈ)2 = π 2 β (π cos π΄)2 = π 2 β π 2 cos2 π΄
In the right triangle BEC
πΈπΆ = π΄πΆ β π΄πΈ = π β (π cos π΄)
(π΅πΈ)2 + (πΈπΆ)2 = (π΅πΆ)2
π 2 β π 2 cos2 π΄ + (π β π cos π΄)2 = π2
π 2 β π 2 cos2 π΄ + π2 + π 2 πππ 2 π΄ β 2ππ cos π΄ = π2
π 2 + π2 β 2ππ cos π΄ = π2
π2 = π2 + π 2 β 2ππ cos π΄
Area of the triangle ABC= 21 (π΄π·)(π΅πΆ) = 21 (π sin πΆ)(π) = 12 ππ sin πΆ

Solution
Let numbers are in ascending values are such that π₯1 , π₯2 , π₯3 , π₯4 , π₯5
Let highest=π₯5 , lowest= π₯1
Range= π₯5 β π₯1 = 10 βΉ π₯5 = π₯1 + 10
Median term π₯3 = 10
Mean=
π₯1 +π₯2 +π₯3 +π₯4 +π₯5

βΉ
π₯1 +π₯2 +π₯3 +π₯4 +π₯5

= 10
βΉ π₯1 + π₯2 + π₯3 + π₯4 + π₯5 = 50
Putting π₯5 = π₯1 + 10, π₯3 = 10
π₯1 + π₯2 + 10 + π₯4 + π₯1 + 10 = 50
2π₯1 + π₯2 + π₯4 = 50 β 20 = 30
Let π₯2 , π₯4 = 10 as mode value βΆ
2π₯1 + 10 + 10 = 30
2π₯1 = 30 β 20
2π₯1 = 10
π₯1 = 5
π₯5 = π₯1 + 10 = 5 + 10 = 15
Hence numbers are 5, 10, 10, 10, 15

The area of rectangle = 2π₯2 + 24π₯ β 39π₯ + 22 = 0
The area of rectangle = 2π₯2 β 15π₯ + 22 = 0
(c) Factorising 2π₯2 β 15π₯ + 22 = 0
2π₯2 β 11π₯ β 4π₯ + 22 = 0
