Answer:
The answer would be 80 ° because 5×( 2 + 13 or x +1 ) is 80
Step-by-step explanation:
ABD is 80°
If DEB is 42 °
∠ ABD = 5(2X+1)
∠ DBC = 3X+6
∠ EBC = Y +135/2
∠ ABD and ∠ DBC are linear pairs
∴ ∠ ABD +∠ DBC = 180
∴ 5(2X+1) + 3X+6 =180
solve for x
∴ x = 13
∴∠ ABD = 5(2X+1) = 5(2*13+1) = 135
∠ DBC = 3x+6 = 3*13+6 = 45
∠ ABD and ∠ EBC are vertical angles
∴ ∠ ABD = ∠ EBC = 135
∴ y +135/2 = 135
∴ y = 135/2
Answer:
1426
Step-by-step explanation:
this question has been asked before and answered incorrectly but people corrected them in the comments.
Answer: a) 1024, b) 1, c) 64 and d) 0.125.
Step-by-step explanation:
Since we have given that
(a) 
As we know that

So, it becomes,

(b) 
As we know that


c) 
As we know that

(d) ![[(8^{-1})(8^{\frac{2}{3}})]^3](https://tex.z-dn.net/?f=%5B%288%5E%7B-1%7D%29%288%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D%29%5D%5E3)
As we know that
![[(8^{-1})(8^{\frac{2}{3}})]^3\\\\=[8^{-1+\frac{2}{3}}]^3\\\\=[8^{\frac{-1}{3}}]^3\\\\=8^{-1}\\\\=\dfrac{1}{8}=0.125](https://tex.z-dn.net/?f=%5B%288%5E%7B-1%7D%29%288%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D%29%5D%5E3%5C%5C%5C%5C%3D%5B8%5E%7B-1%2B%5Cfrac%7B2%7D%7B3%7D%7D%5D%5E3%5C%5C%5C%5C%3D%5B8%5E%7B%5Cfrac%7B-1%7D%7B3%7D%7D%5D%5E3%5C%5C%5C%5C%3D8%5E%7B-1%7D%5C%5C%5C%5C%3D%5Cdfrac%7B1%7D%7B8%7D%3D0.125)
Hence, a) 1024, b) 1, c) 64 and d) 0.125.
V=LWH=20
L is 5 more than W
V=5+W
H is 1 less than W
H=-1+W
easy, sub 5+W for L and -1+W for H in LWH=V=20
20=(5+W)(W)(-1+W)
expand
20=W^3+4W^2-5W
minus 20 both sides
W^3+4W^2-5W-20=0
either factor or graph to find the possible values for W
(W+4)(W^2-5)=0
set each to zero
W+4=0
W=-4
impossible, measures cannot be negative
W^2-5=0
add 5
W^2=5
sqrt both sides
W=√5
sub back
L=5+W
L=5+√5
aprox
7.24 rounded
H=-1+W
H=-1+√5
aprox
1.24 rounded
the dimentions are
√5 by (5+√5) by (-1+√5) or aprox
2.24in by 7.24in by 1.24in
