Answer:
6
Step-by-step explanation:
All triangles equal 180 degrees to this is what I did:
8x + 2 + 70 + 60 = 180
8x + 2 + 130 = 180
8x + 132 = 180
subtract 132 from each side
8x = 48
now divide each side by 8 to isolate the x
x = 6.
Using translation concepts, the y-coordinate of R' will be of -10.
<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 either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
For this problem, the rule is given by:
(x,y) -> (x + 4, y - 7)
y -> y - 7 means that for the image, the 7 is subtracted from the y-coordinate of the pre-image. The y-coordinate of R is of -3, -3 -7 = -10, hence the y-coordinate of R' will be of -10.

Answer:
x = 50°
Step-by-step explanation:
The sum of the measures of the angles of a quadrilateral is 360°
360 - 40 - 80 - 110 = 130
130 is the measure of the quad that is adjacent to the angle of x° and is supplementary to that angle also.
Therefore, x = 180 - 130 = 50
