Step-by-step explanation:
that is the step by step
brainliest please
I actually posted this a while ago and it got answerd by a smart person so here's what I understood
the error is that it assumes that √(x²)=x
because if x is negative, it becomes positive
that's how the 2nd line is wrong
the 2nd line is the first wrong step
it goes from 4-9/2+9/2
so it goes from 4-4.5+4.5
notice the part under the parenthsees
√((4-4.5)²)
if we evaluate 4-4.5, we get -0.5
but by squaring it we get 0.5
-0.5+4.5=4, yes
but when we square it we get
0.5+4.5=5, that is how it works
Answer:
I got one
Step-by-step explanation:
C.converse of the corresponding angles postulate
∠1 = 58° ( alternate angles )
HOPE THIS HELPS:)
STAY SAFE
∠1 and ∠2 form a straight angle and are supplementary, thus
∠2 = 180° - 58° = 122°
.4 is the answer m8
