Answer:
x=24cm
y=20,78cm
Step-by-step explanation:
sen(30)=
-> x*sen(30)=12 -> x=
= 24cm
cos(30)=y/x -> cos(30)= y/24 -> y=24*cos(30)= 20,78cm
Multiply it out first.
90x+225-4=1
Combine like terms.
90x+221=1
Start isolating variable.
90x=-220
x=-220/90=-22/9
The answer is x=-22/9.
Hope this helps!
In order to write the given number in Scientific Notation we have to move the decimal digit 10 places to the right.
Moving decimal to the right means, the exponent of 10 will be negative when the number is written in scientific notation.
Since, we have to move the decimal by 10 digits, the exponent of 10 will be -10.
Therefore, the number written in scientific notation will be:
basically write the triangle in degree language like this is a acute angle because this is a 70* degree angle and talk more
