ANSWER
EXPLANATION
The vertex of the graph is at
The equation of the graph in vertex form is given by the formula,
The above graph has a minimum point, hence
When we put these values into the equation we obtain,
This implies that,
The point (-2,0) lies on the line.
The correct answer is D.
Answer:
-7/15
Step-by-step explanation:
=-4/5 + 1/3
=(-12+5)/15
=-7/15
The x value will be 109°. The straight line formed a 180° angle. Solving the equation yields the angle.
<h3>What are supplementary angles?</h3>
Supplementary angles are two angels whose sum is 180°. When a straight line intersects a line, two angles form on each of the sides of the considered straight line.
Those two-two angles are supplementary angles in two pairs. That is, if two supplementary angles are adjacent to each other, their exterior sides form a straight line.
The straight line formed a 180° angle. The resulting equation is as follows:
⇒x+42°+29°=180°
⇒x=109°
Hence, the value of the x will be 109°
The complete question is:
AB is a straight line.

Its very simple. You see, consider a right angled triangle, and the side opposite to the right angle or the largest side is Hypotnuse and the side the is adjacent to the angle that you choose is the adjacent side.
