Hello,
let x the first angle
5x the second
2/3 x the third
x+5x+2/3x=180
==>20x/3=180
==>x=27 (°)
5x=5*27=135
2/3*x=2/3*27=18
27+135+18=180
Answer:
B. X=0.02
Step-by-step explanation:
The solution to the natural log equation is found by taking antilogs.
ln(x) = -4 . . . . . . . given equation
x = e^-4 . . . . . . . take antilogs
x ≈ 0.0183156
x ≈ 0.02 . . . . rounded to 2 decimal places
_____
<em>Additional comment</em>
Essentially, we use each side of the equation as a power of e.
e^ln(x) = e^(-4)
x = e^-4 . . . . . . . simplified
Choices C and D can be eliminated by the fact that ln(x) for x < 0 is undefined. x cannot be negative.
Answer:
59 cm
Step-by-step explanation:
Given data
we are given the parameter of the circle as
radius= 9.4cm
π = 3.14
We know that
circumference= 2πr
subsitute
C= 2*3.14*9.4
C= 59cm
Hence the circumference is 59 cm
|t + 4| < 10 - 3
|t + 4| < 7
-7 < t + 4 < 7
-7 - 4 < t < 7 - 4
-11 < t < 3.
