If two angles are complementary, then they equal 90 degrees. If one angle is 62 degrees we subtract it from 90 and get 38 degrees.
Depends on triangle. First a triangle equals 180 degrees in total. If you have a square making 90 degrees,the other 2 sides have to add with 90 to make 180. So you add 90 with the number you have and then use the sum to subtract it from 180 making your missing side.
An acute angle is between 0 and 90 degrees. Angles between 90 and 180 degrees are called obtuse angles.
You could rotate it in either direction, like a steering wheel. -- If you rotate the whole plane 90 degrees to the left, then the old x-coordinate of every point becomes its new y-coordinate, and its old y-coordinate becomes its negative x-coordinate. -- If you rotate the whole plane 90 degrees to the right, then the old x-coordinate of every point becomes its new negative y-coordinate, and its old y-coordinate becomes its new x-coordinate.
Assume its a reference angle, meaning it goes from the x axis and than around in the counter clockwise direction. The top half of the graph is 180 degrees, and the first quadrant is 90. Since the angle is between these two numbers,we know its in the second quadrant. 145-90 = 55 degrees. 90-55 = 35. 35 degrees above the negative x axis.
-90 (when you add a negative you simply subtract so -40-50 is -90)
Subtract the angle from 90 degrees and you have the complement Subtract the angle from 180 degrees and you have the supplement
You subtract 90 degrees minus 80 degrees 25'. Note: You should convert the 90 degrees to 89 degrees and 60 minutes first, that way you can easily subtract degrees and minutes.
complementary angles add to 90 degrees subtract from 90 90-35 = 55
subtract 90 from it and find the trig ratio of that and it will be equal to the trig ratio that is over 90 degrees
90 divided by 9 is 10 so you can subtract 9 from 90 for 10 times before you reach 0 if you want to go into negative numbers you can keep subtracting as many times as you like you are sooooooooo wrong WOW. You can subtract 9 once from 90 because once you subtract 9 from 90, 90 becomes 81. That's how I do it
angles are complementary if they equal 90 degrees when added. if you have one angle that's 40 degrees, then the compliment of it is and angle of 50 degrees. the way you can find it is to subtract the angle whose compliment you want to find, and then subtract it from 90. No all wrong this is patrick
When a vector is multiplied by a negative number, it changes direction by 180 degrees but keeps the same magnitude. Therefore, a vector initially acting at 90 degrees would end up acting at 270 degrees (or -90 degrees) after being multiplied by a negative number.
[°C] = ([°F] − 32) × 5⁄9 90 degrees Fahrenheit = 32.2 degrees Celsius
70
to find the complement, subtract 23 from 90. so the answer is 67 degrees
The complement is how much you have left after you subtract the first angle from 90 degrees.
