The answer is B. You had to check the work in the calculator after you showed the work. Two answers gave you whole numbers , then when you plug it in only one of them solved to 180 correctly
Answer:


Step-by-step explanation:

( Being vertically opposite angles)
Vertically opposite angles are always equal.
Move variable to L.H.S and change it's sign
Similarly, Move constant to R.H.S and change it's sign
⇒
Collect like terms
⇒
Subtract 18 from 50
⇒
Divide both sides of the equation by 2
⇒
Calculate
⇒
The value of x is 16
Now, let's find value of m<AFD :
( sum of angle in straight line )
plug the value of x
⇒
Multiply the numbers
⇒
Add the numbers
⇒
Move constant to R.H.S and change it's sign
⇒
Subtract 98 from 180
⇒
Value of m<AFD = 82
Hope I helped!
Best regards!!
1 ) the formula used to calculate the simple interest is
I = Ci*n, f his formula you obtain n , that is the time in years n = I/ Ci, where c is the initial capital, i is the earned interest , and i is he rate of interest,
n = 120/600 (0,025) = 120 / 15 = 8 , at 8 years, you will obtain $ 120 of INTEREST
6 x 270= 1,620
I hope this helped
