Answer:
y = 189.8
Step-by-step explanation:
Apply trigonometric function to find y.
Reference angle (θ) = 50°
Adjacent side = 122
Hypotenuse = y
Apply CAH, since the Hypotenuse and the Adjacent are involved.
Thus:
Cos θ = Adj/Hypo
Plug in the values
Cos 50° = 122/y
y*Cos 50° = 122
y = 122/cos 50°
y = 189.8 (beater tenth)
If the number is between 25 and 35 It would have to be either 28 or 32.
The solution to the system of equations is (3,1)
Step-by-step explanation:
The system of equations represented by graph are:

Solving the system of equations
Let:

Putting value of y from eq(2) into eq(1):

So, Value of x = 3
Putting value of x into eq(2)

So, value of y= 1
So, The solution to the system of equations is (3,1)
