Answer:
There are NO real solutions to this equation as per the study of its discriminant.
Step-by-step explanation:
In order to answer the question, one needs to examine the "discriminant" associated with this quadratic equation.
Recall that the discriminant of a quadratic equation of the form:
is given by:
in our case :
Then the discriminant becomes:
The discriminant is then a negative number, which means that there are NO real solutions (its solutions must involve imaginary numbers)

Answer:
∠A ≈ 72°
Step-by-step explanation:
Fill in the given numbers and do the arithmetic.
cos A = (2.9² +2.5² -3.2²)/(2(2.9)(2.5)) = 4.42/14.5
The inverse cosine function is used to find the angle, given its cosine.
A = arccos(4.42/14.5)
∠A ≈ 72°
