Angle x and angle y are complementary. Angle x is supplementary to a 128 degree angle. What are the measures of angle x and angl
1 answer:
The measurement of angle x is 52° and y is 38°
Step-by-step explanation:
Let us define supplementary and complementary angles first.
Supplementary angles is pair of angles whose sum is 180°
While complementary angles sum up to 90°
Given
That x and y are complementary and x is supplementary to 128.
This means that sum of x and 128 is 180°
So,
x = 52°
It is also given that x and y are complementary which means that
Hence,
The measurement of angle x is 52° and y is 38°

Answer:
Step-by-step explanation:
There are 3 ways to find the other x intercept.
1) Polynomial Long Division.
Divide x^2 - 3x + 2 by the binomial x - 2, because by the Factor Theorem if a is a root of a polynomial then x - a is a factor of said polynomial.
2) Just solving for x when y = 0, by using the quadratic formula.
.
So the other x - intercept is at (1, 0)
3) Using Vietta's Theorem regarding the solutions of a quadratic
Namely, the sum of the solutions of a quadratic equation is equal to the quotient between the negative coefficient of the linear term divided by the coefficient of the quadratic term.
And the product between the solutions of a quadratic equation is just the quotient between the constant term and the coefficient of the quadratic term.
These relations between the solutions give us a brief idea of what the solutions should be like.
