Although there i no triangle given as the question requires, I am still going to answer because I understand it.
ABC is a right angled triangle. The triangle is 90° at C.
The trigonometric ratio sine is given by, sine = opposite/hypotenuse .
Cosine = adjacent/hypotenuse
So therefore, Sin A = 24/30
= 4/5
Cos A = 18/30
= 3/5
3^5 is the same as 3*3*3*3*3. which is 243
Answer:
21.8
Step-by-step explanation:
hii so basically first we find the area of the 9 by 8 and subtract the area of the semicircles.
area of circles are πr^2, so in this situation
π4^2 which is 16π.
with this, the semicircle which is half a circle would give us
16π/2 which is 8π.
but then, we have two semicircles removed so we would have as an answer:
(9*8)-8π+8π
72-16π
then you would have to round so
16π is around 50.2
so 72-50.2 is 21.8
i hope this helped you <33
Answer:
The predicted value of x = 2
Step-by-step explanation:
y = 4.2x - 3 is the given equation.
Now, y = 5.4
Putting in the above equation, we get
5.4 = 4.2x - 3
or, 5.4 + 3 = 4.2x
or, 8.4 = 4.2 x
⇒ x = 8.4/4.2
⇒ x = 2
