Answer:
x =128
Step-by-step explanation:
Applying the law of sines, the measurement indicated are:
7. AB = 24.1 cm
8. BC = 28.0 in.
<h3>What is the Law of Sines?</h3>
Law of sines is: sin A/a = sin B/b = sin C/c.
7. AB (c) = ?
BC (a) = 22 cm
A = 180 - 138 - 22 = 20°
C = 22°
Apply the law of sines:
sin 22/AB = sin 20/22
AB = (sin 22 × 22)/sin 20
AB = 24.1 cm
8. BC (a) = ?
A = 58°
AC (b) = 33 in.
B = 180 - 58 - 33 = 89°
Apply the law of sines:
sin 58/BC = sin 89/33
BC = (sin 58 × 33)/sin 89
BC = 28.0 in.

Answer: 0.06x
Step-by-step explanation:
- An algebraic expression is an expression consist of integer constants, variables, and algebraic operations.
The given statement: A number is 30% of 20% of the number x.
The required algebraic expression would be:
30% of 20% of x
[we divide a percentage by 100 to convert it into decimal]
Hence, the required algebraic expression would be :
0.06x
Answer:
Step-by-step explanation:
J(x)=b(x)
3x-2=|x+2|
3x-2=±(x+2)
when 3x-2=x+2
3x-x=2+2
2x=4
x=4/2=2
when 3x-2=-(x+2)
3x-2=-x-2
4x=-2+2=0
x=0
it is rejected as 0-2≠|0+2|
or -2=2
so x=2
