Answer:
sin(A) = 3/5. , cos(A) = 4/5
Step-by-step explanation:
sine = opposite/hypotenuse cosine = adjacent/hypotenuse
Answer:
About 40% I think-
Step-by-step explanation:
Basically, you change 2/5 into a percentage and you should get 40 percent.
Answer:
i dont either
Step-by-step explanation:

Above, I changed the fraction form of x and y into exponential form so it is easier to see the differentiation. Now, we can differentiate:

Now that we have dy/dx, we can plug in the x, which is 4, and the y, which is 4/19. We know these values of x and y because your question stated y(4) = 4/19.
Answer:
x=136
Step-by-step explanation:
To find the measure of the sum of the interior angles use the formula (n-2) times 180 where n is the number of sides.
A quadrilateral has 4 sides. (4-2) times 180. 2 times 180=360
The sum of the interior angles of a quadrilateral is 360.
x+47+95+82=360
x+ 224 = 360
x= 136
