Answer:
2 ^ 15
Step-by-step explanation:
2 ^9 * 2 ^ 2 * 2 ^ 4
When we multiply numbers with the same base, we can add the exponents
a^ b * a^ c = a^(b+c)
2 ^9 * 2 ^ 2 * 2 ^ 4
2 ^ ( 9+2+4)
2 ^ 15
Answer
Proof of (a)
Disagree with the ΔABD = ΔCBD by the SAS congruence postulate .
SAS congurence property
In this congurence property two sides and one angle of the two triangles are equal .
(1) BD = BD ( Common sides of the ΔABD and ΔCBD )
(2) AB =BC (B is the midpoint of the AC i.e it bisect AC in the two equal parts.)
but equal angles are not given
therefore disagree with the ΔABD = ΔCBD by the SAS congurence postulate .
Proof of (b)
SSS congurence property
In this congurence property three sides of the two triangles are equal .
In the ΔABD and ΔCBD .
(1) BD = BD ( Common sides of the ΔABD and ΔCBD )
(2) AB =BC (B is the midpoint of the AC i.e it bisect AC in the two equal parts.)
(3) AD=CD (Given )
ΔABD = ΔCBD by the SSS congurence theorem
Hence proved
Answer:
x=40 y=5
Step-by-step explanation:
Answer: x= 83
Why? It’s on a straight line which is 180 degrees so take 97 and subtract it from 180
180-97=x
X= 83
Hope this helps
