33.	If nth term of the progression 3,10,17...... and 63,65,67......be same then find the value of n.
Answer» Answer: n=13 Step-by-step explanation: 1) 3,10,17...... First TERM = a = 3 Common difference = d = 10-3 = 17-10 = 7 Formula of nth term : $a_n=a+(n-1)d$ Substitute the values : $a_n=3+(n-1)7$ $a_n=3+7n-7$ $a_n=7n-4$ ---A 2) 63,65,67...... First term = a = 63 Common difference = d = 65-63= 67-65 = 2 Formula of nth term : $a_n=a+(n-1)d$ Substitute the values : $a_n=63+(n-1)2$ $a_n=63+2n-2$ $a_n=61+2n$ --B Now we are given that the nth term of both the progression are same EQUATE A and B So, $61+2n=7n-4$ $65 = 5n$ $13 = n$ Hence the VALUE of n is 13

33.

If nth term of the progression 3,10,17...... and 63,65,67......be same then find the value of n.

Answer»

Answer:

n=13

Step-by-step explanation:

1) 3,10,17......

First TERM = a = 3

Common difference = d = 10-3 = 17-10 = 7

Formula of nth term : $a_n=a+(n-1)d$

Substitute the values :

$a_n=3+(n-1)7$

$a_n=3+7n-7$

$a_n=7n-4$ ---A

2) 63,65,67......

First term = a = 63

Common difference = d = 65-63= 67-65 = 2

Formula of nth term : $a_n=a+(n-1)d$

Substitute the values :

$a_n=63+(n-1)2$

$a_n=63+2n-2$

$a_n=61+2n$ --B

Now we are given that the nth term of both the progression are same

EQUATE A and B

So, $61+2n=7n-4$

$65 = 5n$

$13 = n$

Hence the VALUE of n is 13

41.

if the sides of a triangle are 3m, 4m and 6M long, determine whether the triangle is a right angled triangle.with process

Answer»

Given sides = 3m, 4m, 6m

According to right angle triangle, if the sum of squares of two SMALLER sides is equal to sum of larger SIDE.

=> ( Smaller side's Sum )² = ( Hypotenuse )²

=> ( 3² + 4² ) = ( 6 )²

=> 9 + 16 = 36

=> 25 = 36 But we KNOW that, 25 ≠ 36.

Hence they dont form a right angled triangle.

47.

A tower stands vertically on the ground. from a point which is 15 m away from the foot of the tower , the angle of elevation of the top of the tower is 45°.what is the height of the tower

Answer»

Angle of ELEVATION = 45

Then,

15M/HEIGHT of tower = tan45

15m/height of tower = 1

Height of the tower = 15m

OR

Since the angle is 45

The right triangle formed by the tower and the point on the ground has ONE angle to be 45 degrees

So, it is an isosceles right triangle

Therefore,

DISTANCE from tower = Height of tower = 15m
