Sin=opositeside/hyptonuse
cos=adjacentside/hyptoonse
try and draw a diagram
pretend we gots
acute angle is on left side
right angle is below obtuse angle

so sinA=7/25=left side/hypotonuse
so we need to find other side
pythagorean theorme

a²+b²=c²
7²+b²=25²
49+b²=625
b²=576
b=24

so

sinA=o/h
cosA=a/h

7=o
25=h
24=a

cosA=24/25

I think it is 142cm^2. What I did to work this out is, 236 divided by 5= 47.2 ( to get the surface area of a 1cm cylinder) then multiply by 3 = 141.6 then round

Find 5 Rational Numbers Between 1 and 2 using (a+b/2) where a=1 and b=2.
mojhsa [17]

Answer:

There are two ways to find the rational number between any two numbers. I will tell you an easy method to find it.

As we have to find 5 rational numbers between 1 & 2

Take 5 and add 1 to it i.e. 5+1= 6

Now take the first number and multiply and divide it by 6 i.e.

1x6/6 = 6/6

Also take the second number and multiply and divide it by 6 i.e.

2x6/6= 12/6

This is done to convert 1 & 2 into rational number i.e. in form of p/q

Now we have two numbers 6/6 and 12/6 so five rational numbers between them are

7/6, 8/6, 9/6, 10/6, 11/6

The values of these number you can check will be between 1 & 2. Actually between any two number there are infinite number of rational numbers.

Reduce then multiply. <br><br> 7/9 x 3/4 = ?<br><br> Example :
ziro4ka [17]

First, we are going to want to see if there are any terms we can simplify. By examining the numerators and denominators of our functions, we can see that we can remove a 3 from the denominator of the second function and the numerator of the first function. This would be represented as:

\dfrac{7}{9} \cdot \dfrac{3}{4} = \dfrac{7}{3} \cdot \dfrac{1}{4}


Now, we can multiply the fractions. Remember that to multiply fractions, simply multiply both the numerators over both the denominators, as shown below:

\dfrac{a}{b} \cdot \dfrac{c}{d} = \dfrac{ac}{bd}


By applying this information, we can solve for the product of the fractions:

\dfrac{7}{3} \cdot \dfrac{1}{4} = \dfrac{7}{12}


Our answer is \boxed{\frac{7}{12}}.
