Suppose two angles are complementary If one angle has a measure of 62 what is the measure of the second angle?
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.
How do you find the Missing side of a right angle triangle?
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.
What is a rotation of 90 degrees about the origin?
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.
Is an angle between 90 degrees and 180 degrees an acute angle?
An acute angle is between 0 and 90 degrees. Angles between 90 and 180 degrees are called obtuse angles.
How do you draw a 145 degree angle?
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.
What is negative 40 plus negative 50?
-90 (when you add a negative you simply subtract so -40-50 is -90)
Find the complement of a angle?
Subtract the angle from 90 degrees and you have the complement Subtract the angle from 180 degrees and you have the supplement
How do i find the angle complementary to the angle 80 25'?
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.
How do you find the complimentary angle to 35?
complementary angles add to 90 degrees subtract from 90 90-35 = 55
How do you find trigonometric ratios of angles greater than 90 degrees?
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
How many times can you subtract 9 from 90?
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
What is a complement of an angle and how do you get 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
What is positive 90 plus -20 equal to?
70
What is the measure of an angle that is the complement of and angle?
The complement is how much you have left after you subtract the first angle from 90 degrees.
What is the complement of a 23 degree angle?
to find the complement, subtract 23 from 90. so the answer is 67 degrees
How do you find the missing angle of a quadrilateral with angles of 90 90 130?
First, find the sum of your given angles, 90, 90, and 130. You get 310. Now subtract that from 360 since all quadrilaterals have exactly 360 degrees. Your answer is 50 degrees.
If two angles of a triangle each measure 45 degrees what is the third angle?
If two angles of a triangle each measure 45 degrees, the third angle measures 90 degrees. This is because of the Triangle Sum Theorem - The sum of the measure of the interior angles of a triangle is 180 degrees. If you know that two of the angles total to be 90 degrees, you can subtract that 90 degrees from the total 180. The result is 90 degrees.
