Answer:
Rounded to the nearest tenth the solutions to the equation are:
x = -1.7 and x = -6.3
Step-by-step explanation:
Since this is a quadratic equation of the form:
Use the quadratic formula, which tells you that the solutions would be given by:
So in our case, the quadratic formula gives:
which gives us two real solutions:
x = - 1.654792
x = -6.345207
Which rounded to the nearest tenth give:
x = -1.7 and x = -6.3
We know: The sum of measures of angles in the triangle is equal 180°.
x - the measure of the second angle
2x - the measure of the first angle
x - 8° - the measure of the third angle
The equation:
