Answer» Step-by-step explanation: we know that, sum of all ANGLES of the triangle are of 180. therefore, a+b+c=180 a+b=180-c by DIVIDING both SIDES with 2 (a+b)/2 = 90-c/2 by applying tan on both sides.... tan a+b/2 = tan {90 -c/2} tan a+b = COT c/2 hence proved..

If a,b,,c are angles of a triangle abc.show that tan a+b/2=cot c/2

Answer»

Step-by-step explanation:

we know that,

sum of all ANGLES of the triangle are of 180.

therefore, a+b+c=180

a+b=180-c

by DIVIDING both SIDES with 2

(a+b)/2 = 90-c/2

by applying tan on both sides....

tan a+b/2 = tan {90 -c/2}

tan a+b = COT c/2

hence proved..

47.	Which term of the AP:3,15,27,39,...will be 132 more than 54th term.please give step by step
Answer» Answer: 65th term Step-by-step explanation: In APs, nth term is GIVEN by a + (n - 1)d , a is FIRST term and d is common difference. Here, a = first term = 3 d = 15 - 3 = 12 Let nth term be 132 more than 54th term = > 3 + (n - 1)12 = 132 + {3 + (54 - 1)12} = > 3 + 12n - 12 = 132 + 3 + (53)12 = > 12n - 9 = 135 + 636 = > 12n = 135 + 636 + 9 = > 12n = 780 = > n = (780/12) = > n = 65 65th term is 132 more than 54th term.

Which term of the AP:3,15,27,39,...will be 132 more than 54th term.please give step by step

Answer»

Answer:

65th term

Step-by-step explanation:

In APs, nth term is GIVEN by a + (n - 1)d , a is FIRST term and d is common difference.

Here,

a = first term = 3

d = 15 - 3 = 12

Let nth term be 132 more than 54th term

= > 3 + (n - 1)12 = 132 + {3 + (54 - 1)12}

= > 3 + 12n - 12 = 132 + 3 + (53)12

= > 12n - 9 = 135 + 636

= > 12n = 135 + 636 + 9

= > 12n = 780

= > n = (780/12)

= > n = 65

65th term is 132 more than 54th term.
