Answer:
This is multiplicative identity in which 4✖️1=4
Step-by-step explanation:
Hope it will help you:)
Boys to girls is 4:5.......added = 9
so 4/9 are boys and 5/9 are girls
Given:
In the given triangle,
With respect to y, Perpendicular = 10 cm and Base = 8 cm
To find the value of y.
Formula
By Trigonometric Ratio we get,

Now,
Putting the values of perpendicular and base we get,

or, 
or, 
Rounding off to the nearest tenth, we have;

Hence,
The value of y is 51.3°.
Constant is occurring continuously over a period of time so C is the correct answer because C is constant for a period of time
Answer:
270cm^2
Step-by-step explanation:
The side length is irrelevant and does not matter.
The area of a triangle is found by multiplying the base by the height and then dividing that by two.
For this problem it would be...
30*18=540
540/2=270
So the area would be 270cm^2
