What is the value of

ipn [44]

All angles in a triangle add up to 180 degrees.
We are finding the value for both y's (they are congruent) so I'll just plug in the answers to the problem.
Let's start with 54.
54*2=108
108+72=180
The answer is then A, 54 degrees

Answer:

$\textbf{Option C}\\$

Step-by-step explanation:

$\textup{You have to substitute values of x from the table and see if it satisfies the given condition.}\\\textup{For example in option A, $(-2,-2)$ is the point given.}\\\textup{Substitute $x = -2 $ in $y = -x^2 + 3x $}\\\textup{We get $y = -10 \ne -2$. Eliminate option $A$ and $B$ from this.}\\$

$\textup{Now we will check for $x = 1$ as the values of $y$ differ in options $C$ and $D$.}\\$i.e., $ \textup{For} $x = 1, y = - {1}^2 + 3(1) $\\$\implies y = 2 \ne 4$, \textup{eliminating Option $D$.}\\\textup{Also substitute other values for $x = -1, 0, 2$ and the answer can be verified.}\\\textup{\textbf{Hence, option $C$ will fit this function.}}$
