899-891 = 8 = (2)^{3}

891-864 = 27 = (3)^{3}

864-800 = 64 = (4)^{3}

as we can see the pattern between differences of consecutive numbers is of type (n)^{3}

so x-800 = (5)^{3},this implies that x= 675

Solution:

QUESTION: 128

If tan θ + cot θ = 2, 0 < 0 <90°, then the value of θ is

Solution:

tan θ + 1/tanθ = 2

tan^{2} θ + 1 = 2 tan θtan2θ+1=2tanθ

sec^{2} θ = 2 tan θ

hypotenuse^{2} / adjacent side^{2} = 2 opposite side / adjacent side

hypotenuse^{2} / adjacent side = 2* opposite side

hypotenuse/adjacent side = 2* opposite side/adjacent side

1/cos θ = 2 sin θ

sin θ. cos θ = 1/2

We know that, when θ = 45 degrees, this relation will hold true.

Therefore, option C is the right answer.

QUESTION: 130

The shadow of a tower standing on a level ground is found to be 40 metre longer when the suns altitude is 30° than when it is 60°. Find the length of the tower,

Solution:

We know that, length of shadow will be equal to the adjacent side and the height of tower is the opposite side of the triangle.

We have been given that difference in lengths of shadows = 40m.

Length of shadow = h tan A.

h tan 60 - h tan 30 = 40

h√3 - h/√3 = 40

(3h -h)/√3 = 40

2h = 40√3

h = 20√3 m.

Option A is the right answer.

QUESTION: 131

The length of the shadow of a tower is 9 metres when the sun’s altitude is 30°. What is the height of the tower ?

1887x+1887y = 1887

divide the equation by 1887

x+y = 1 ...................................(4)

now

x^{2}−y^{2} = (x-y)*(x+y)

put values from (3) & (4)

therefore, x^{2}−y^{2} = 7*1 = 7

QUESTION: 134

In two similar triangles ABC and MNP, if AB = 2.25 cm, MP = 4.5 cm and PN = 7.5 cm and m ∠ACB = m ∠MNP and m ∠ABC = m ∠MPN, then the length of side BC , in cm, is

QUESTION: 137

AC is a chord of circle whose centre is at 0. If B is any point on the arc AC and ∠OCA = 20°, then the magnitude of ∠ABC is

Solution:

OC=OA=radius .Hence , the angles opposite to these sides must also be equal.

So, ∠OCA=20 = ∠OAC. Hence , ∠AOC = 180 - 20 -20 = 140.

Now consider a point D on the major at of AC and join D to A & C. This gives △ADC.

So . ∠AOC= 2*∠ADC So, ∠ADC= 140/2 = 70

Now , ADCB is a cyclic quadrilateral sum of whose all opposite is 180.

So, ∠D + ∠B = 180 .

∠B = 180 - 70 = 110.

QUESTION: 138

The co-ordinates of the vertices of a right-angled triangle are P (3, 4), QA(7, 4) and R (3, 8), the right-angle being at P. The co-ordinates of the orthocentre of APQR are

Solution:

Since it is a right angled triangle, the 2 sides adjacent to the right angle will be altitudes. The third altitude must meet at the vertex at which these 2 sides meet.

Hence, the vertex that contains the right angle is the orthocentre. From the points given, we can clearly see that (3,4) is the orthocentre. Option B is the right answer,

QUESTION: 139

The value of (sec θ + cosec θ) when θ = 45°, is

Solution:
