Answer:

Step-by-step explanation:
x = 65° ( vertically opposite angles )
y = 71° ( alternate angles )
The sum of the 3 angles in a triangle = 180° , then
x + y + z = 180° , that is
65° + 71° + z = 180°
136° + z = 180° ( subtract 136° from both sides )
z = 44°
So x = 65°, y = 71° , z = 44°
Part A:
For this case we have the following equation:
10x2 - 3x - 1 = 0
The radicand of the equation is:
root (b ^ 2 - 4 * a * c)
Substituting values:
root ((- 3) ^ 2 - 4 * (10) * (- 1))
root (9 + 40)
root (49)
49> 0
Therefore, the function has two real roots.
Part B:
For this case we have the following equation:
16x2 - 2x - 5 = 0
Factoring we have:
(2x + 1) * (8x-5) = 0
The solutions are:
x = -1/2
x = 5/8
The method of factoring is usually faster when solving quadratic equations.
