you subtract the other angle from 180 and that should give you your answers
A quadrilateral with 3 acute angles and 1 obtuse angle is known as a scalene trapezoid. In this type of quadrilateral, three of the angles are less than 90 degrees (acute angles), while one angle is greater than 90 degrees (obtuse angle). The sides of a scalene trapezoid are of different lengths, and the opposite sides are not parallel. This distinguishes it from other types of quadrilaterals such as rectangles or parallelograms.
A linear equation is defined as an equation that contains only the first power of the unknown quantity. For example, 5x - 3 = 7 where "x" is the unknown quantity is a linear equation. If an equation contains an unknown quantity having a higher power than 1, then the equation ceases to be a linear equation. For example, 3x2 + 5x + 7 = 0 is a non linear equation known as a quadratic equation, because the unknown quantity "x" has a power of 2. Similarly, equations containing unknowns with higher powers such as x3, x7, x12 are all non linear equations.
It depends on what other information you have: area, circumference, radius, length of arc subtending a known angle, measure of angle for a known arc length etc.
To find an unknown value in a proportional relationship, you can set up a ratio equation based on the known values. For example, if you have a proportional relationship expressed as ( \frac{a}{b} = \frac{c}{d} ), where ( a ) and ( b ) are known values, and ( c ) is the unknown, you can cross-multiply to solve for ( c ) by rearranging the equation to ( c = \frac{a \cdot d}{b} ). This allows you to calculate the unknown value while maintaining the proportional relationship.
Well the three angles in a triangle all add up to 180° so if you add the two known angles and take it away from 180 you'll get your unknown angle.
An angle of 140 degrees is an obtuse angle because it is greater than 90 but less than 180 degrees.
You can solve by substituting (x) for the unknown angle and (x + 40) for the angle plus 40 degrees and set the equation as: x + (x + 40) = 90 (then simplify) 2x + 40 = 90 (then isolate the known from unknown by subtracting 40 from each side of the equation) 2x = 50 (divide both sides by 2 to solve for x) x (the unknown angle) = 25 degrees now you can substitute the value of the angles to prove the equation.
Obtuse Also:Any angle that is greater than 0o and less than 90o is an acute angle. * Think of something "cute" being tiny. Any angle that is 90o is a right angle. Any angle that is greater than 90o and less than 180o is an obtuse angle. * Think of obtuse as being something that is large in size. Any angle that is 180o is a straight line. And finaly, any angle that is larger than 180o is known as a reflexive angle.
A perfect angle could be considered a 90 degree angle. A 90 degree angle is also known as a "Right Angle". Other types of angles are: Acute, Obtuse, Reflex, and Straight.
To write an equation for a given problem, first identify the unknown quantity you want to find. Then, use variables to represent the unknowns and write an equation that relates the known quantities to the unknown quantity. Solve the equation to find the value of the unknown.

First, an acute angle is an Angle that is less than a right angle (<90°) Secondly, an obtuse angle is one that is more than a right angle but less then a straight angle (<180°) then, the complementary angles of a pair of angles is 90° or a Right angle and the complement of an acute angle is the amount needed of an unknown angle (against known angles) to make 90° or a right angle a supplementary angle are a pair of angles which, when Added together, make 180° or a straight line. and the suplement to an angle is the value of an unknow angle to to be added on to make 180°
180 minus two known angles = unknown angle
An angle measuring 110 degrees is classified as an obtuse angle, which is greater than 90 degrees but less than 180 degrees. In geometric terms, an angle measuring 110 degrees is known as an obtuse angle because it is greater than a right angle (90 degrees) but less than a straight angle (180 degrees). This angle can be found in various geometric shapes and can be used to calculate other angles or solve geometric problems.
