Answer:
and
Step-by-step explanation:
It is given that
and
To find:
Now, since Line CAF and EAB intersect each other therefore,
(vertically opposite angles are equal) ...(1)
Now, (Sum of linear pair)
Now From eq. (1)
(vertically opposite angles are equal)
Step-by-step explanation:
f(x) = y
8x = y
x = y/8
We can note the inverse as
Or, if you want the function to be expressed as depending on variable x
3s + 2p = 85.50....multiply by -1
3s + 4p = 123
--------------------
-3s - 2p = -85.50 (result of multiplying by -1)
3s + 4p = 123
--------------------add
2p = 37.50
p = 37.50/2
p = 18.75 <=== cost of the pants
3s + 4p = 123
3s + 4(18.75) = 123
3s + 75 = 123
3s = 123 - 75
3s = 48
s = 48/3
s = 16 <=== cost of each shirt
Answer:
80 degree angle is the right answer
