Answer:
Segment A B and Segment Z W
Step-by-step explanation:
we know that
If two figures are congruent, then its corresponding sides and its corresponding angles are congruent
In this problem
Sides C D and Y X are congruent,
sides C B and Y Z are congruent,
sides Z W and A B are congruent,
sides A D and X W are congruent
so
ABCD≅WZYX
The corresponding sides are
AB and WZ
BC and ZY
CD and YX
AD and WX
That means
AB ≅ WZ
BC ≅ ZY
CD≅ YX
AD ≅ WX
The corresponding angles are
∠A and ∠W
∠B and ∠Z
∠C and ∠Y
∠D and ∠X
That means
∠A ≅ ∠W
∠B ≅ ∠Z
∠C ≅ ∠Y
∠D ≅ ∠X
therefore
The answer is
Segment A B and Segment Z W
Cos A = (b^2 + c^2 − a^2) / 2bccos A = (10.4)^2 + (29.2)^2 − (22.2)^2) / (2 x 10.4 x 29.2)cos A = (108.16 + 852.64 − 492.84) / 607.36cos A = 0.77 m<A = cos−1(0.77)
m<A = 39.6
from here....you're already known the answer is C.
because only m<A = 39.6
but if you want to make sure you get it right, so you'll calculate another angle...
cos B = (a^2 + c^2 − b^2) / 2accos B = (22.2)^2 + (29.2)^2 − (10.4)^2) / (2 x 22.2 x 29.2)cos B = (492.84 + 852.64 − 108.16) / 1296.48cos B = 0.9544 m<B = cos−1(0.9544)
m<B = 17.4
So now you know for sure answer is C.
Hope it helps
Answer: 24 cm^2 (24 centimeters squared)
Step-by-step explanation:
6^2 + 8^2 = 36 + 64 = 100 = 10^2
(1/2)*6*8 = 24 cm^2.
Answer:
(-8) + (-8) + (-8) + (-8)
Step-by-step explanation:
Since Yan is descending ; we represent his movement as being negative.
Number of rungs descended before stopping = 4
Number of stops = 8
Given that no extra steps was taken ;
Number of ladder rungs descended :
4 rungs per stop for 8 stops
- 4 * 8 = - 32 rungs
Another way to write the product :
Number of stops added in number of rungs descended :
(-8) + (-8) + (-8) + (-8)
