Is there meant to be a picture attached with this?
we know that
The sum of the internal angles in the triangle must be
degrees
see the attached figure with letters to better understand the problem
Step 
<u>Find the measure of the angle x</u>
In the triangle ABC

solve for x



therefore
<u>the answer Part a) is</u>
the measure of angle x is 
Step 
<u>Find the measure of the angle z</u>
we know that
--------> by supplementary angles
substitute the value of x



therefore
<u>the answer Part b) is</u>
the measure of angle z is 
Step 
<u>Find the measure of the angle y</u>
In the triangle ACD

solve for y




therefore
<u>the answer Part c) is</u>
the measure of angle y is 
the slope of the line is y = -1/2x -2

Mode is 6
Option A is correct.
Step-by-step explanation:
We need to find the mode for the given data set:
6,8,3,5,6,4,7,7,0,1,6
<u>Definition of Mode</u>
- Mode is the most repeating value of data set.
Finding mode of data set: 6,8,3,5,6,4,7,7,0,1,6
Arranging data in ascending order:
0,1,3,4,5,6,6,6,7,7,8
SO, most repeating value is 6
So, mode is 6
Option A is correct.
