Answer:
Step-by-step explanation:
(21²+10²)½ = 23.25= 23.3
I think it’s 6. There are 4 squares and 4 triangles. 2 triangles put together turn into a square, so that would make 2 extra squares. 4+2=6.
If the three sets of corresponding sides of two triangles are in proportion, the triangles are similar. SAS for similar triangles is NOT the same theorem as we used for congruent triangles.
Answer:
Step-by-step explanation:
Re-written, I believe the equation is:
(W+23)+5=W+(23+5)
With this, the parenthesis have nothing multiplying into it, so we can drop the parenthesis to get:
W+23+5=W+23+5
Which is the same thing.
So I'd assume it is the Associative property, because you are combining the like terms of 23 and 5.
Hope this helps!
