know what is the third side length
the difference between the 2 other sides < the greatest side of triangle < the sum of 2 other sides
so here the answers here could be ( 10- 17 - 20)
10-8 < 13 < 10+8
13-8 < 17 < 13+8
13-8 < 20 < 13+8
Answer:
B and C
Step-by-step explanation:
I hope this helps :)
Linear
Non linear
Non linear
Linear
If the equation shows a straight line then it’s a linear equation if the equation doesn’t shows a straight line then it’s non linear
The angle measured from the normal to the mirror will be
.. arctan(14/11.5) ≈ 50.6°
recall that the reference angle, is the angle made by the terminal point with the x-axis.
Check the picture below.
