First calculate the missing angle
. By knowing all angles in triangle have a sum of 180°.
Now we required to use angle functions in a right triangle. The cosine of
is equal to the relation of side
and hypotenuse
.
Now we solve this for hypotenuse.
Now put in the numbers.
So we know the length of hypotenuse and length of side
therefore side
can be calculated using Pythagorean theorem:
.
Solve for side
.
So there you go. If you have any questions feel free to ask.

Answer:
Step-by-step explanation:
Given the quadratic equation;
x² - 6x + 3 = 0
To find the roots of the quadratic equation, we would use the quadratic formula;
Note: the standard form of a quadratic equation is ax² + bx + c = 0
a = 1, b = -6 and c = 3
The quadratic equation formula is;
Substituting into the formula, we have;
Or
k = 0 means the parabola has one zero, because the vertex is just on the x-axis. k > 0 means the parabola has none zeros, because the vertex will be above the x-axis and it will not intersect the x - axis.
129 degrees is the correct answer for the missing angle number 1 :)
