Find, correct to the nearest degree, the three angles of the triangle with the given vertices. p(1, 0), q(0, 1), r(4, 4)

The angles of the triangle are 81.870°, 81.870° and 16.260°, respectively.

We can determine the angles of the triangle by using the definition of dot product as follows:

(1)

(2)

(3)

Where:

Please remember that Norm is determined by the Pythagorean Theorem.

If we know that , and , then the angles of the triangle are, respectively:

The angles of the triangle are 81.870°, 81.870° and 16.260°, respectively.

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
