18/5 = x/100
1800 = 5x
----- -----
5 5
360 = x
You can use proportion to solve your equation to figure out the x value so you have corresponding ratios
Answer:
Option a and b both are correct.
Step-by-step explanation:
We have been given the information that is: n is added to 15 less than 3 times itself.
The result is 101.
So, the number is 15 less than 3 times to itself means: 3n-15
And n is added to it that means:
n+(3n-15)
And its result is 101 so,
n+(3n-15)=101
After simplification of above expression gives:
4n-15=101.
Therefore, Option a and b both are correct.
Answer:
Step-by-step explanation:
cos²<em>x</em> = 1-sin²<em>x</em> = 1-(5/13)² = 144/169
cos<em>x</em> = √(144/169) = 12/13
tan<em>x</em> = sin<em>x</em>/cos<em>x </em>= (5/13)/(12/13) = (5/13)×(13/12) = 5/12
Answer:
Is not the answer but is how to do it. Sorry
Step-by-step explanation:
you got the value of a=2
use the formula
S=n/2 [2a+(n-1)d] then calculate d from here..
put it in t=a+(n-1)d
The angle formed by the ribbon and the pole is 29°
Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Let θ represent the angle formed by the ribbon and the pole.
Hence:
The angle formed by the ribbon and the pole is 29°
