Tea is made up of milk and tea ratio of 2 to 9. how much tea can be made using 1 litre of milk
Ilya [14]
You can solve it like this

2=milk (a); 1=milk (b)
9=tea (a); x= tea (b)

2:9=1:x (then multiply means and the extremes)
(means are 9 and 1; extremes are 2 and x)

9=2x
9/2= x
4.5 or 4 1/2=x

Therefore, using 1 litre of milk, we can have 4 1/2 tea.

Can someone help me on this Proofs problems? It's just number one and two.
leonid [27]

See Explanation

Step-by-step explanation:

1. By interior angle sum Postulate of a triangle.

m\angle a+ m\angle y +m\angle z= 180\degree.... (1)\\\\m\angle a+ m\angle w +m\angle x= 180\degree.... (2)\\\\

From equations (1) & (2), we find:

m\angle a+ m\angle y +m\angle z= m\angle a+ m\angle w +m\angle x\\\\m\angle y +m\angle z= m\angle w +m\angle x\\

Hence proved

2. In \triangle PQS, \: \angle QSR is exterior angle.

Therefore, by remote interior angle theorem, we have:

m\angle QPS + m\angle PQS= m\angle QSR\\\\x + m\angle PQS= 2x\\\\m\angle PQS= 2x-x\\\\m\angle PQS = x.... (1)\\\\m\angle QPS = x.... (given).... (2)\\

From equations (1) & (2), we find:

m\angle PQS = m\angle QPS\\\\\therefore \angle PQS \cong \angle QPS\\\\\therefore PS \cong QS\\(sides\: opposite \: to\: congruent \:\angle s) \\\\

\therefore \triangle PQS is an isosceles triangle.

Thus proved.
