Answer:
C. 39°
Step-by-step explanation:
The measure of the angle where the chords cross is the average of the measures of the subtended arcs.
x = (AB +CD)/2 = (28° +50°)/2 = 78°/2
x = 39°
The coefficient of the variable in the expression 4-3x-7+6 is 3
Answer:
See the graph of the given linear equation shown below.
Explanation:
Given the linear equation : x+y = -2
We make a table for values of x and y;
x y = -2-x
0 -2
-2 0
1 -3
Now, plot these three points (0, -2) , (-2, 0) and (1, -3) on the coordinate plane.
You can see the graph as shown below.
Using translation concepts, it is found that the image of point R after the transformations is given by: (1,-2).
<h3>What is a translation?</h3>
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
The first transformation is:
(x,y) -> (x - 3, y + 5).
Hence:
(2,-3) -> (-1, 2).
For the rotation of 180º counter clockwise, the rule is:
(x,y) -> (-x,-y).
Hence the image is:
(-1,2) -> (1,-2).
