To solve this problem you must apply the proccedure shown below:
1. You have that the ratio of the measures of the three angles is
2. The sum of the interior angle of a triangle is
3. Let's say that the measure of each angle is multiplied by the ratio. Therefore, you can write the following equation and solve for
:
4. Therefore, the measure of each angle is:
The answer is:
The solutions for the quadratic equation are given as follows:
x = -1, x = 7/5
<h3>What is a quadratic function?</h3>A quadratic function is given according to the following rule:
y = ax^2 + bx + c
The solutions are:
In which:
For this problem, the equation is:
5x² - 2x - 7 = 0.
Hence the coefficients are a = 5, b = -2 and c = -7, and then the solutions are found as follows:
The solutions are:
x = -1, x = 7/5
