Answer:
The correct option is 4.
4) Doing two distance formulas to show that adjacent sides are not the same length.
Step-by-step explanation:
Parallelogram is a quadrilateral which has opposite sides equals and parallel. Example of a parallelogram are rhombus, rectangle, square etc.
We can prove that a quadrilateral MNOP is a parallelogram. If we find the slopes of all four sides and compare those of the opposite ends, same slopes would indicate the opposite sides are parallel, hence the quarilateral is a parallelogram. We can also find the distance of two opposing sides, and slopes of twp opposing sides to determine whether it is a parallelogram or not. The most difficult approach is that diagonals bisect each other at same point.
However, using only two distance formulas will not give us enough information to determine whether a side is parallel or not.
Answer:
4
Step-by-step explanation:
first take away the 5 years (13-5=8)
then divide it by 2 (8÷2=4
The correct answer is 18.7.
So I kind of went an indirect way but I can explain it all. I ignored the 15°. The box in the right correct means that angle is 90°. Since a triangle is always 180°, I subtracted 90 and 15 from 180. That gives you 75°. Now that you know that you can use tangent from SOH CAH TOA. So... tan75= x/5 which turns into 5tan75°. Plug that into a calculator and you get 18.66 which rounds to 18.7.
If you need anymore help I'm here. Hope I helped :) Good luck!
