What is the sum of the interior angles of an 8 sided convex polygon?
Take the number of sides and subtract 2, then multiply that answer by 180. (8-2) x 180 = 6 x 180 = 1080
What is the third angle in a triangle if the other two are 38 degrees and 95 degrees?
180-38-95. The sum is always 180 in a triangle, so just subtract the other two from 180 to get the third.
Sum is to add as what is to subtract?
When you add, your answer is the sum.When you subtract, your answer is the difference.
What is the sum of angles in a octadecagon?
( n x 180 ) - 360wheren is the number of sides.In other words,take the number of sides or your polygon and multiply that by 180.then, subtract 360 from that result.that is your answer.An octadecagon has 18 sides.( 18 x 180 ) - 360 = 2880The sum of the interior angles of an octadecagon is 2880 degrees.
Find the measure of the third angle?
In euclidean (plane) geometry, the sum of the interior angles of any triangle is 180 degrees. Add the two angles you know (right angles = 90 degrees) and subtract that sum from 180. Without more information on the problem, that's the most I can assume
What is the measure of the third angle if you have 47 degress and 62 dregress?
I assume you mean a TRIANGLE. The angles in a triangle will sum up to 180 degrees. So sum your two angles and subtract that from 180.
How do you find the value of x when you have three other numbers?
add the three numbers the subtract 180 from your sum
What is the formula for finding the sum of angles?
Subtract the number of sides of the polygon by two then multiply it by 180Formula:Interior angle sum = (s-2) x 180 (With s being the number of sides the polygon has.
Why do you need to subtract 2 from a polygon?
For any polygon: (number of sides-2)*180 = sum of interior angles
Prove that the sum of the measures of the three angles of every triangle is 180 degrees?
Angle a plus angle b subtract from 180 equals angle c
What is the sum of the interior angles of an 8 sided convex polygon?
Take the number of sides and subtract 2, then multiply that answer by 180. (8-2) x 180 = 6 x 180 = 1080
What is the third angle in a triangle if the other two are 38 degrees and 95 degrees?
180-38-95. The sum is always 180 in a triangle, so just subtract the other two from 180 to get the third.
How do you find a missing measure in a acute triangle?
Add the 2 sides together then subtract the sum from 180˚. Here is an example. 50˚ + 50˚= 100˚ 180˚− 100˚ = 80˚ ←Your answer
How do you determine the third angle of a right triangle if 2 angles are known?
simple... first we know that a triangle has a sum of 180 degrees therefore you add the two known angles then subtract their sum from 180 which gives you the measure of the third angle
How do you find the angle of an triangle?
you know a triangle always measure 180 degrees the two angles you are given add them together then subtract 180-_____the blank is for the sum of the two addends
What is the sum of both angles 180?
If both angles are 180, their sum is 360!If both angles are 180, their sum is 360!If both angles are 180, their sum is 360!If both angles are 180, their sum is 360!
