1,0472 rad
Step-by-step explanation:
ANGLE MEASURES
Generally two measuring systems are used:
1. The sexagesimal system, whose unit is the degree: º
A sexagesimal degree is the amplitude of the angle resulting from dividing the circumference into 360 equal parts.
2. The radial system whose unit is the radian: rad
A radian is the measure of the center angle of a circle whose arc length coincides with the length of its radius.
<u>CONVERSION OF GRADES TO RADIANS
</u>
To convert an angle of degrees to radians or vice versa, what must be done is a rule of three, considering that:
360° = 2π radians
Calculation
(60° * 2π rad) /360° = 1.0472 rad
The opposite of 10/7 is -10/7.
The reciprocal of 10/7 would be 7/10.
I think it is C) I’m pretty sure
Bearing in mind that, if you multiply, any integer whatsoever by 2, you end up with a even integer, 17*2, or 19*2, 88*2 you name it, you get an even number
now, you can get an odd integer by simply going from an even integer, back or forth, so if you have an even number of say 24, 24 - 1, 23, 24+1, 25, 23 and 25 are the odd ones next to 24
so.. let's pick some number, let's say hmm "a", we know 2*a is even, so 2a, thus, 2a +1 or 2a -1 is an odd one.... let's use hmm 2a + 1 as our first odd integer
to jump from an odd integer to another, you simply add 2, 3+2, 5, 5+2, 7 and so on
so... our first one is 2a + 1, so the next consecutive one, will then be (2a+1)+2
and next consecutive after that is (2a+1+2)+2
so our three consecutive odd integers are then
2a + 1
2a + 3
2a + 5
now, 4 times the middle is 4(2a+3)
the sum of the first and last is (2a+1) + (2a+5)
now, two more than that is just (2a+1) + (2a+5) + 2
thus
4(2a + 3) = (2a + 1) + (2a + 5) + 2
solve for "a"
