Hey!~
I believe the correct answer is C, a postulate .
Hope this helps and have a great day!

You seem to be saying that Y=4/X+SQRT X +0.2 -5X, and that x is given as 4/5. To evaluate <span>Y=4/X+SQRT X +0.2 -5X, replace each occurrence of x with 4/5:
y = 4 / (4/5) + sqrt(4/5) + 0.2 - 5(4/5)
= 5 + 2 / sqrt(5) + 0.2 - 4
Can you simplify this further?

Use either the distance formula or the Pythagorean Theorem. i suggest you plot the 2 given points and draw the line segment CD connecting these points.
What is the horiz. distance between the 2 points? The vertical distance?
If you'd square the horiz. distance and also square the vertical distance, and then add these two squares together, and finally take the positive square root of this sum, you'll have the distance cd. Round it off to the nearest tenth.
Answer:
125 degrees.
Step-by-step explanation:
m < CBD = m < A + m < C ( by the External Angle of a Triangle theorem).
= 58 + 67 = 125 degrees.
