So to use an equation to find it, we have to find the missing number.
1.6x=80
Now divide:
80÷1.6= 50
Let's check to see if we're right.
50×.6= 30+50= 80
So they required 50 grams of cheese.
This kind of triangle is acute triangle because on the given three angles, none of them does not exceed more than 90°.

Missing Part of Question:</h3>
Some information was missing so I am attaching the complete question.

</h3><h3>
Step-by-step explanation:</h3>
Given Equation is:
Step (a)
Let, A = 5 * 3 * 10
A = 150
Step (b)
Multiplying both sides of equation (1) with A = 150, we get,
Multiplying both sides of equation (1) by 10 we get,
Step (c)
Solving Equation (a), we get
Solving Equation (b), we get
Step (d)
Step (e)
Both methods work the same because as long as we multiply (or divide) the same amount to the total equation, the equation balances itself out. For example, consider an equation
x = 2;
If we multiply it by 10 on both sides we will get
10x = 20,
If we simplify the above equation, however, we will get the same initial equation.
x = 20/10
x = 2
I think you have to sketch the graph
Number 6 is b and number 5 is a and number 7 is c
