Based on the given nomenclature of angles, I think the illustration would look like that shown in the attached picture. The common vertex is point B, that's why the middle point of the given angles is B. Now, according to Angle Addition Postulate, the individual interior angles should sum up to the total angle. So, the equation would be
m∠ABD = m∠ABC + m∠CBD
m∠ABC = m∠ABD - m∠CBD
m∠ABC = 85° - m∠CBD

27 units squared?
Step-by-step explanation:
I think it is 27, look at the Parallelogram bh formula, base times h equals area.
X=2.412 is the correct answer
Answer:
The slope is -3/4 and the y-intercept is 1.
Step-by-step explanation:
B is the point where the line cross the y-axis, or vertical axis. Slope is the steepness of the line. Determined by rise over run. When the slope goes down 3 units, the slope goes to the right 4 units.
Answer:
-3
Step-by-step explanation:
First step to this is to replace the variables with their coordinated values. Remember to use parentheses.
4(2)-2(2+4)+1=?
We can start to simplify.
4(2)-2(6)+1
Then---
8-12+1
-4+1
Final Answer (-3)
