Find the missing lengths in the triangle. Round to the nearest tenth if necessary.
a.
	
a = 8.5 cm, b = 14.7 cm
	
c.
	
a = 14.7 cm, b = 8.5 cm
b.
	
a = 8.5 cm, b = 12 cm
	
d.
	
a = 5.7 cm, b = 14.7 cm

anonymous · Answer

thats also a possibilty but you have to then use pythagorams theory

anonymous · Answer

and that is a rectangle, not a square

anonymous · Answer

@marloesiee so how do i find the awnser

anonymous · Answer

by multiplying 40 by the square root of 2

anonymous · Answer

@marloesiee  why 40? 

there is an image on top that shows it is a triangle im doing special right triangles?

anonymous · Answer

because the side length is 40 ft right?

anonymous · Answer

@marloesiee

anonymous · Answer

either way you still get 56,57 ft

anonymous · Answer

.
	
a = 8.5 cm, b = 14.7 cm
	
a = 8.5 cm, b = 12 cm
14.7 cm, b = 8.5 cm
5.7 cm, b = 14.7 cm
those are the awnser choices! @marloesiee
