If cot theta = 1/3 find all other trignometric ratios

Answer»

Answer:

Step-by-step explanation:

COT theta =b/p,

by the pythagoras theorem FIND hypotenous,

h²=p²+b²,

h=√(3)²+(1)² ,

h=√10,

All the trigonometrics RATIOS are:

sin theta=p/h=3/√10.

cos theta=b/h=1/√10.

tan theta=p/b=3/1.

cosec theta=h/p=√10/3.

sec theta=h/b=√10.

cot theta=1/3.

64. The sum of interior angles of regular polygon is thrice the sum of its exterior angle. The polygon is a. hexagon c. decagon b. octagon d. nonagon​

Answer»

Answer:

HEXAGON

Step-by-step explanation:

Sum of the EXTERIOR angle of a polygon = <klux>360</klux>^{0}

Sum of the INTERIOR angle of a polygon = <klux>120</klux>^{0}

If in a regular polygon, each interior angle = 120 deg, then each exterior angle = 180–120 = 60 deg. So the polygon has 360 deg/60 deg = 6 sides. The figure is a regular hexagon.

6x+4y=10,2x-2y=2 by elimination method

Answer»

Step-by-step explanation:

multiplying 2X - 2y = 2 with 2

4x - 4y = 4 {EQUATION 1}

6X + 4y = 10 {equation 2}

eliminating

10x = 14

x = 7/5

2x - 2y = 2

2 (7/5) -2y = 2

14/5 - 2 = 2y

2.8 - 2 = 2y

y = 0.8 / 2

y = 2/5

Find the sum of all two digit numbers are divisible by 7 ans 728 and this problem

Answer»

Answer:

Step-by-step EXPLANATION:

CONSIDER the lesser case, the SUM of all one digit numbers divisible by 7.

There are two, 7 and -7. Adding 7 to -7 we get zero.

There’s no need to go through the process of finding all the two digit numbers that are divisible by 7, because it is immediately obvious that each will have a negative and a positive counterpart, and that each will thus sum to zero.

2 TIMES 7 is 14, -2 times 7 is -14, so on and so forth.

The sum of the positive such numbers is 728, but the sum of negative such numbers is -728, so the sum of all such numbers is 0.
