2x - 4 < 5 and -(2x - 4) < 5
Well, that would be imposible to solve. You are missing the radius. But if the radius was 5, then it would be simple.
Ф=240.0 degreese = 4.19 radians.
x=-2.50
y=-4.33
If the radius is different, then check out this website that me and my team has put togather. http://www.intmath.com/complex-numbers/convert-polar-rectangular-interactive.php
The sum of exterior angles in total: 360 degrees
6th angle = 78+50+89+37+65= 319
Then 360-319= 41 degrees
Answer:
24 seconds
Step-by-step explanation:
Given data
Blues flashes= 8 seconds
Red flashes= 12 seconds
Let us find the least common factor of 8 and 12
8= 2,4,8,16,24
12=2,3,4,6,24
Hence the number seconds is 24 seconds
Answer:
(4) 0
Step-by-step explanation:
<u>Given:</u>
- cos²27°×cos²34°×...×cos²167 = ?
<u>Looking at the angles measures, they form series of: </u>
This is AP with the first term of 27 and common difference of 7
<u>We can see one of the terms of this AP is 90</u>
Since cos 90° = 0 ⇒ cos²90° = 0 and therefore given series equals to zero as one of the terms of multiplication is zero.
<u>So correct answer choice is</u> Option 4) 0
