For this case we have that a quadratic equation is of the form:
The roots are given by:
We have the following equation:
We look for the roots:
We have to:
So:
We have two imaginary roots:
Answer:
Answer:
Step-by-step explanation:
take 51 degree as reference angle
using sin rule
sin 51=opposite/hypotenuse
0.77=YZ/9
9*0.77=YZ
6.93=YZ
6.9=YZ
Since you haven't provided the data to answer the problem, I have my notes here that might guide you solve the problem on your own:
Now, consider a triangle that’s graphed in the coordinate plane. You can always use the distance formula, find the lengths of the three sides, and then apply Heron’s formula. But there’s an even better choice, based on the determinant of a matrix.
Here’s a formula to use, based on the counterclockwise entry of the coordinates of the vertices of the triangle
(x1<span>, </span>y1), (x2<span>, </span>y2), (x3<span>, </span>y3<span>) or (2, 1), (8, 9), (1, 8): </span>A<span> = </span>x1y2<span> + </span>x2y3<span> + </span>x3y1<span> – </span>x1y3<span> – </span>x2y1<span> – </span>x3y2<span>.</span>

Answer: First option is correct.
Step-by-step explanation:
A number in an expression is a term that contains no variables.
So, it is known as constant term.
if any term is with variable or variables, then it can't be consider as a number.
Then, it becomes only a term.
But if there is no variables in a term is present, then it is called to be number.
Hence, First option is correct.
