Answer:
I won't be able to solve the entire question but I will give you the formula and show you how to find the answer
4) 1.65x + 1.36y = 118.17 (i)
x + y = 79. (ii)
From the (i) equation you get
1.65x = 118.17 - 1.36y
x = (118.17 - 1.36y)/1.65 (iii)
Substituting the value of (iii) in (ii)
(118.17-1.36y)/1.65 + y = 79
When you solve it you will get the answer
After that find the value of x and y and multiply them by 1.65 and 1.36 respectively.
Then find their difference and see which class sold more and by how much.
Hope this helps you!

Step-by-step explanation:
step 1. wow! 670° I think you mean 67°
step 2. the 3 internal angles of a triangle add up to 180°. let x be the third angle
step 3. x + 102 + 67 = 180
step 4. x + 169 = 180
step 5. x = 11°.
1)
=> <span>m∠2 = 2x +13
=> </span><span><span>m∠1 = </span> 4x - 1
Since YP angle bisector the angles with be equal to each other,
</span>
m∠1 = <span>m∠2
2x + 13 = 4x - 1
2x - 4x = -1 -13
-2x = -14
x = 7
</span>
All other questions are to be done in that way, don't be lazy :P
