Proof

Reference to the β–± ABCD in the figure

Area of the β–± ABCD= π‘π‘Žπ‘ π‘’ Γ— π‘Žπ‘™π‘‘π‘–π‘‘π‘’π‘‘π‘’
Area of the β–± ABCD= (𝐷𝐢) Γ— (𝐴𝐿)
Let 𝐷𝐢 = 𝑏 ,𝐴𝐿 = β„Ž ⟹
Area of the β–± ABCD= (𝑏)(β„Ž)
Area of the β–± ABCD= π‘β„Ž
Area of the β–³ADC= 12 π‘β„Ž
Area, A, of circle of radius r

𝐴 = 2πœ‹π‘Ÿβ„Ž

For the triangle shown,

=

𝑐
sin 𝐢

π‘Ž2 = 𝑏2 + 𝑐 2 βˆ’ 2𝑏𝑐 cos 𝐴
Area= 12 π‘Žπ‘ sin sin 𝐢

Proof

7

Reference to the triangle

8

Let altitude= 𝐴𝐷
Also in the right angle triangle ADC
𝐴𝐷
𝐴𝐢

= sin 𝐢 ⟹ 𝐴𝐷 = 𝐴𝐢 sin 𝐢

Since 𝐴𝐢 = 𝑏 ⟹ 𝐴𝐷 = 𝑏 sin 𝐢
Also in the right triangle ABD
𝐴𝐷
𝐴𝐡

= sin 𝐡

Since 𝐴𝐡 = 𝑐 ⟹

𝐴𝐷
𝑐

= sin 𝐡 ⟹ 𝐴𝐷 = 𝑐 sin 𝐡

Since
𝐴𝐷 = 𝑐 sin 𝐡 and 𝐴𝐷 = 𝑏 sin 𝐢
⟹ 𝑐 sin 𝐡 = 𝑏 sin 𝐢 ⟹
𝑐
sin 𝐢

=

𝑏
sin 𝐡

Similarly from the same triangle ABC, drawing BEβŸ‚ AC

9

In the right triangle AEB
𝐡𝐸
𝐴𝐡

=

𝐡𝐸
𝑐

= sin 𝐴 ⟹ 𝐡𝐸 = 𝑐 sin 𝐴

Similarly
In the right triangle BEC
𝐡𝐸
𝐡𝐢

= sin 𝐢

Since 𝐡𝐢 = π‘Ž ⟹

𝐡𝐸
π‘Ž

= sin 𝐢 ⟹ 𝐡𝐸 = π‘Ž sin 𝐢

Now

10

𝐡𝐸 = 𝑐 sin 𝐴 and 𝐡𝐸 = π‘Ž sin 𝐢 ⟹ 𝑐 sin 𝐴 = π‘Ž sin 𝐢
Or

𝑐
sin 𝐢

=

π‘Ž
sin 𝐴

Combining the results
π‘Ž
sin 𝐴

=

𝑏
sin 𝐡

=

𝑏
sin 𝐡

=

𝑐
sin 𝐢

and

𝑐
sin 𝐢

=

π‘Ž
sin 𝐴

𝑐
sin 𝐢

Drawing BEβŸ‚ to AC in the same triangle ABC

In the right angled triangle AEB
cos 𝐴 =

𝐴𝐸
𝐴𝐡

=

𝐴𝐸
𝑐

⟹ 𝐴𝐸 = 𝑐 cos 𝐴

Also

11

we have:

(𝐡𝐸)2 + (𝐴𝐸)2 = (𝐴𝐡)2 Or
(𝐡𝐸)2 = (𝐴𝐡)2 βˆ’ (𝐴𝐸)2 = 𝑐 2 βˆ’ (𝑐 cos 𝐴)2 = 𝑐 2 βˆ’ 𝑐 2 cos2 𝐴
In the right triangle BEC
𝐸𝐢 = 𝐴𝐢 βˆ’ 𝐴𝐸 = 𝑏 βˆ’ (𝑐 cos 𝐴)
(𝐡𝐸)2 + (𝐸𝐢)2 = (𝐡𝐢)2
𝑐 2 βˆ’ 𝑐 2 cos2 𝐴 + (𝑏 βˆ’ 𝑐 cos 𝐴)2 = π‘Ž2
𝑐 2 βˆ’ 𝑐 2 cos2 𝐴 + 𝑏2 + 𝑐 2 π‘π‘œπ‘ 2 𝐴 βˆ’ 2𝑏𝑐 cos 𝐴 = π‘Ž2
𝑐 2 + 𝑏2 βˆ’ 2𝑏𝑐 cos 𝐴 = π‘Ž2
π‘Ž2 = 𝑏2 + 𝑐 2 βˆ’ 2𝑏𝑐 cos 𝐴
Area of the triangle ABC= 21 (𝐴𝐷)(𝐡𝐢) = 21 (𝑏 sin 𝐢)(π‘Ž) = 12 π‘Žπ‘ sin 𝐢

Q 14 The range, mode, median and mean of five positive integers are all equal to 10
...
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 βˆ’ π‘₯1 = 10 ⟹ π‘₯5 = π‘₯1 + 10
Median term π‘₯3 = 10
Mean=

π‘₯1 +π‘₯2 +π‘₯3 +π‘₯4 +π‘₯5
5

⟹

π‘₯1 +π‘₯2 +π‘₯3 +π‘₯4 +π‘₯5
5

= 10

⟹ 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 βˆ’ 20 = 30
Let π‘₯2 , π‘₯4 = 10 as mode value ⟢
2π‘₯1 + 10 + 10 = 30
2π‘₯1 = 30 βˆ’ 20
2π‘₯1 = 10
π‘₯1 = 5
π‘₯5 = π‘₯1 + 10 = 5 + 10 = 15
Hence numbers are 5, 10, 10, 10, 15

(a) Write down an expression, in terms of x, for the height of the rectangle

Solution
(a)The area of the triangle = 12 β„Žπ‘₯ = 11π‘π‘š2

(b) The area of rectangle = (π‘₯ + 1)(β„Ž + 2) = π‘₯β„Ž + 2π‘₯ + β„Ž + 2 = 39π‘π‘š2
The area of rectangle = π‘₯β„Ž + 2π‘₯ + β„Ž + 2 = 39π‘π‘š2
Putting β„Ž =

The area of rectangle = 22π‘₯ + 2π‘₯2 + 22 + 2π‘₯ = 39π‘₯

32

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