15.	The value of 6 radiansa)343 38'9''b)343 14' 12''c)343 38'11''
Answer» ANSWER: c) 343 38' 11'' Step-by-step explanation: To convert radians to degrees, multiply (180/π) with the radian measure So 6 rads= 6×(180/π) By calculating, we get 6×(180/π)= (540×7)/11= 3780/11 = [343×(7/11)]° Now, we don't WRITE degrees in fractions 1°= 60'(also called minutes) Now we will only convert the fraction part and leave the 343 part as it is. We will add it later in the final answer. So, 7/11= (7/11)×60= 420/11= [38×(2/11)]' Now, minutes are also not written in seconds 1'= 60"(also called as seconds) Now we will only convert the fraction part and leave the 38 part as it is. We will add it later in the final answer. So, 2/11= (2/11)×60= 120/11 = 10.9"(which we round off to 11) So the final COUNT is 343°38'11" Hope it helps. Thank you.

The value of 6 radiansa)343 38'9''b)343 14' 12''c)343 38'11''

Answer»

ANSWER:

c) 343 38' 11''

Step-by-step explanation:

To convert radians to degrees, multiply (180/π) with the radian measure

So 6 rads= 6×(180/π)

By calculating, we get

6×(180/π)= (540×7)/11= 3780/11

= [343×(7/11)]°

Now, we don't WRITE degrees in fractions

1°= 60'(also called minutes)

Now we will only convert the fraction part and leave the 343 part as it is. We will add it later in the final answer.

So, 7/11= (7/11)×60= 420/11= [38×(2/11)]'

Now, minutes are also not written in seconds

1'= 60"(also called as seconds)

Now we will only convert the fraction part and leave the 38 part as it is. We will add it later in the final answer.

So, 2/11= (2/11)×60= 120/11

= 10.9"(which we round off to 11)

So the final COUNT is 343°38'11"

Hope it helps.

Thank you.

Three angles of quadilateral are equal and fourth angle measures 72° what is the measure of each of the equal angles?

Answer»

Answer:

96°

Step-by-step EXPLANATION:

SUM of ANGLES of a QUADRILATERAL = 360°

x+x+x+72° = 360°

3x+ 72° = 360°

3x= 360°-72°

3x =288°

x = 288/3

x= 96°

Find the other zeroes of the polynomial 2x4 +7x3-19x2-14x+30 if two of it's zeroes are 3/2 and -5

Answer»

p(x) = 2x4 + 7x3 - 19x2 -14x +30

if ZEROES are root2 & -root2

it becomes x2 - 2

so, q(x)= x2-2

then p(x)/q(x) gives 2x2 + 7x - 2
