Let x represent the larger angle and y the smaller. Solve the following:

x+y=180

x-y=40

The second equation tells us that x=y+40. Plugging this into the first equation, we get,

(y+40)+y = 180

2y+40=180

2y=180-40=140

y=140/2=70

So, y=70 and x=70+40=110.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What if the measure of the third angle of an triangle if one angle is 45 degrees and the other is 93 degress?

Since the sum of all three angles is 180 degrees, the third angle is 180 - 45 - 93 =Since the sum of all three angles is 180 degrees, the third angle is 180 - 45 - 93 =Since the sum of all three angles is 180 degrees, the third angle is 180 - 45 - 93 =Since the sum of all three angles is 180 degrees, the third angle is 180 - 45 - 93 =

The sum of the angles in a triangle is 180 degrees.


A Angle that have a sum of 180 degrees?

well to have a sum you need more than one angle. a triangle is a good example of a sum of angles getting to 180 degrees. all triangles angles sum to 180 degrees


What is the sum of two supplementary angles?

How do you find the angle of triangle if their sum and difference is given?

In plane Euclidean geometry there are 3 angles in any triangle that add up to 180 degrees and if given 2 angles the sum of the 2 angles minus 180 will give the measure of the 3rd angle


Do triangles have at least 2 acute angles?

Yes. The sum of the angles in a triangle is 180° All angles in a triangle must be greater than 0° which means that the sum of any two angles must be less than 180° If two angles are right angles (90°), their sum is 180° which is not less than 180°; thus at most one angle can be a right angle. If one angle is a right angle and another is an obtuse angle (greater than 90°), then their sum is greater than 180°, which is not less than 180°; thus there can be at most one of a right angle and an obtuse angle. If two angles are obtuse angles, their sum is greater than 180°, which is not less than 180°; thus there can be at most one obtuse angle. If there is at most one right angle or an obtuse angle, there must be at least two acute angles.

What is the third angle of a triangle if the sum of the other two angles is 148 degrees?

The sum of the angles of a triangle is 180 degrees. If the sum of two of a triangle's angles is 148, then the third angle must be 180 - 148 = 32 degrees.
