Answer:
17. 49
18. 62
Step-by-step explanation:
alright so all u gotta know here is that all triangles add up to 180 degrees
17. 50+83= 133
180-133= 49 degrees
18. 44+74= 118
180-118 = 62 degrees
A linear pair of angles has a common side, and the vertex is on the line designated by the points denoting the non-common sides.
Consider the first choice:
... the common sided is RL, and the other two points are P and M. Point R (the vertex of the angles) is not on line PM. (In fact, line PM is not shown on the diagram.)
In the second choice, the given angles do not have a common side. (They are actually "vertical" angles.)
In the 3rd choice, the common side is RN, and vertex point R is found on line MO. These angles <em>are</em> a linear pair:
... - MRN and NRO
Multiply bath sides by (-13)
Step 1:(-13).a/(-13) <= -16(-13) ===> . Mistake since she the < sign into >
Step 2: a<=208 is the right answer
Step 3: The line should go from 208 to the left & not to the right
48

The expression is 8x-(5x+8)
The simplifies is 3x-8 because 8x-(5x+8)=8x-5x-8 and 8x-5x=3x
