When you want to find a reflex angle do you subtract if from 180 or 360?

It's not clear what you're subtracting.
A reflex angle is any angle between 180° and 360°.

What shape has 3 right angle's 1 obtuse and 1 reflex angle?
The dimwit shape. if you want a joke keep reading, there are 3 types of people, those who can count and those who can't. if you dont get this google it.
What do you do when you want to find the longest side?
Well, it depends. If you are trying to find the hypotenuse, then you go from the right angle and up. The side you across from right angle is the hypotenuse.
How do you find a missing angle on a triangle?
You must use the formulas you know that describe the properties of triangles to relate the information you're given to the size of the unknown angle. Do you want to know the measurement / size of the angle. The internal angles of a triangle add up to 180 degrees. If you know two angles then add them together eg 60 + 30 = 90 now subtract 90 from 180, 180-90 = 90 So the missing angle is 90 degrees
A supplement of an angle is four times as large as the angle find the measure of the angle?
You start with two equations y+x=90 and 4x+y=180 and y is the given angle So if you want to figure out what x is you have to substitute an equation for y. so it ends up being 4x+90-x=180 and then you solve for x add the x's and subtract 90 from both sides giving you 3x=90 and then x=30 But you want to get y so you plug it back into the equation y+x=90 So your answer will equal 60. I hope this helps :)
How do you find the unknown angle of a triangle?
If you have two other angles, then add up those 2 and subtract that from 180. if you have all 3 sides then use the law of cosines: a squared = b squared + c squared - 2bc (cos A) If you have one angle and the 2 included sides, use the law of cosines as well. if you have an angle and the length of its opposite side, and the side opposite to the angle you want, then use the law of sines: sin A/ a = sin B/ b if you have the angle and the length of its opposite side and another angle, use the law of sines to figure out the unwanted angle anyway and then follow situation 1.
What does a reflex angle look like?
I want to seee a picture of a reflex angle
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
How do you get the answer 116 to the problem an angle is 12 degrees less than twice its supplement find the angle?
Supplementary angles add up to 180 degrees You can solve for the supplementary angle first. You can solve for the other directly, but the math is a little more involved. Let A be an angle Start with the supplementary angle. A + ??? = 180 The angle you want is 12 less than twice as big A + (2A - 12) = 180 Solve for A: 3A - 12 = 180 3A = 192 A = 64 Remember A is the supplementary angle, so subtract the angle we solved for (A) from 180 to find the angle you want. 180 - 64 = 116

When is it useful to find the LCM or Greatest common factor in a problem?
Find the GCF when you want to simplify a fraction. Find an LCM when you want to add and subtract fractions.
Why should you find a LCM?
Finding an LCM will help when you want to add and subtract fractions.
How do you find the length of a right angle?
the angle is an angle and therefore doesn't have a length. If you want to find the length of the hypotenuse - the leg across from the right angle - it is the square-root of the other two legs each squared.
Why is it important to find the LCM of 2 numbers?
It will help when you want to add and subtract unlike fractions.
