Answer:
Sum of the interior angles of the triangle is 180°.
According to the above problem,

<h3><u>y=26</u><u>°</u> is the right answer.</h3>
Answer:
Thanks
Step-by-step explanation:
Answer:
The area of shaded sector
Formula A = (θ / 360°) × πr²
θ=360°-140°=220°
r=18yd
We have A=(220/360)×3.14×(18)²
=621.72yd²
Area of sector is621.72yd².
Answer:
The graph in the attached figure
Step-by-step explanation:
we have the ordered pairs
(-4,9),(-1,3),(0,1),(2,-3)
Using a graphing tool
Plot the given ordered pairs in the coordinate plane
Remember that
In a ordered pair (x,y), the first coordinate is the location of the point in the x-axis and the second coordinate is the location of the point in the y-axis
see the attached figure
The graph represent a line
<em>Find the equation of the line</em>
Find the slope
take two points

The equation of the line in slope intercept form is equal to

we have

substitute
