Answer: Same-side interior angles are NOT always congruent.
a) Parallel for both line segments have the same slope = -5/4
b) 55º
Step-by-step explanation:
a) To verify the parallelism of these line segments, It's necessary to find the slope of each one. Parallel lines share the same slope value:

b) If ∠DAB = 125°, what is the measure of ∠CBA? Justify your reasoning.
Those beams do not form a parallelogram because:
Using the formula of distance between those points

So this is a trapezoid. And two adjacent angles within a trapezoid are supplementary, so If ∠DAB = 125º then 180 - ∠CBA=55º
Step-by-step explanation:
first you'll have to cut the triangle in half to make the right angle. when u do the side is whatever the num is 132-??= thats the answer. and then add all of the area nums and then u get the num
Answer:

Step-by-step explanation:
Surface area of cone is given as:
Surface Area (S.A) = πr(r + l)
Where,


Take π as 3.14
Plug the given values into the formula to find the surface area.
