Answer:
12.0
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the trig function relating the adjacent side of an angle in a right triangle to the hypotenuse:
Cos = Adjacent/Hypotenuse
Filling in the given values, we have ...
cos(24°) = 11/x
Multiplying this equation by x/cos(24°), we get ...
x = 11/cos(24°) ≈ 12.0
Answer:
x = 117
Step-by-step explanation:
Given
11 - = 0 ( subtract 11 from both sides )
- = - 11 ( square both sides )
(- )² = (- 11)²
x + 4 = 121 ( subtract 4 from both sides )
x = 117
Step-by-step explanation:
In both the fractions the numerator is less than the denominator thereby indicating that the decimal equivalent is definitely less than one.
Now for A-
We are making the denominator to a multiple of 10.
Now for B-
Using normal long division, divide 4 by 15.
;reminder at each step;calculation of the decimal equivalent
15×2=30;10 ;0.2
15×6=90;10 ;0.26
15×6=90;10 ;0.266
15×6=90;10 ;0.2666
15×6=90;10 ;0.26666
and so on....
Therefore we can see that the reminder is remained constant throughout so there the decimal equivalent is non-terminating.
