Step-by-step explanation:
Using Snell’s law ( n1 sin θi = n2 sin θr ) at point A gives
1) sin i1 = n sin r1
2) i1 = n r1
3) i1 = α1 + β1
4) r1 = β1 - γ
5) α1 + β1 = n(β1 - γ)
6) sin i2 = n sin r2
7) i2 = n r2
8) i2 = α2 + β2
9) r2 = β2 + γ
10) α2 + β2 = n(β2 + γ)
11) α1 + α2 = (n - 1)(β1 + β2)
12) 1/s + 1/s' = (n - 1)(1/R1 + 1/R2)
13) 1/f = (n - 1)(1/R1 - 1/R2)
14) 1/s + 1/s' = 1/f
We are given the data that David has been reimbursed with $3390 driving 600 miles and his expenses are <span>$60 a day for food and lodging and $0.65 per mile. The equation is 3390 = 60 x + 0.65 * 600 = 60 x +390 where x is the number of days. To determine x, we transpose 390 to the other side and divide the equation by 60. x is equal to 50 days.</span>
Step 1
Given;
Required; To find the similarity postulate or theorem that applies.
Step 2
Both triangles share one side AG
They also have a common angle;
Side AG = 10 units and ∠AGT ≅ ∠AGB.
Thus, options A and B are discarded.
Step 3
Now, as for the SAS criteria, we need two sides to be congruent and their included angles to be congruent.
But, as no other information is given, we cannot determine whether the given triangles are congruent or not.
Therefore, the answer is; Option D
