Answer: (-9 ± 3√5) / 2
Step-by-step explanation:
Since our equation is in the form of ax² + bx + c = 0, we'll use the quadratic formula to solve the equation, plugging our values in:
(-9 ± √9²-4(1)(9)) / 2(1)
(-9 ± √81 - 36) / 2
(-9 ± √45) / 2
Here, we can simplify √45 by finding pairs of factors that equal 45, and have one of the factors be able to be square rooted:
(-9 ± √9·√5) / 2
(-9 ± 3√5) / 2
I hope this helps! :)
The complementary angles are angles that add up to 90°.
It is required to find the pair of angles is complementary.
In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle and corner whether constituting a projecting part or a partially enclosed space.
Solution:
When the sum of two angles is equal to 90° degrees, they are called complementary angles. For example, 30° and 60° ,45° and 45° ,80° and 10° are complementary angles.
Therefore, the complementary angles are angles that add up to 90°.
