<u>Answer</u>
1) TanФ = 5/12
2) CosФ = 12/13


<u>Explanation</u>
SecФ = 1/CosФ

Cos = adjacent/hypotenuse
SecФ= 13/12
cosФ = 12/13

This means that the adjacent is 12 and hypotenuse is 13. 
Opposite = √(13²-12²)
                = √25
                = 5

Tangent = opposite/adjacent
TanФ = 5/12

Sine = opposite/hypotenuse 
SinФ = 5/13

To compute a student's Grade Point Average (GPA) for a term, the student's grades for each course are weighted by the number of
tia_tia [17]

Answer:

2.89, rounded to the nearest hundredth

Step-by-step explanation:

Given that GPA is weighted by credits, we must first multiply each grade by its credit amount and sum those up to weigh the credits. Then, we divide by the total amount of credits to get the GPA per credit.

So, we start with math,

3.7 *5 + 1.8 *3 + 2.8 * 5 + 2.8 * 4 = 49.1 as the total GPA weighted per credit.

Then, to find the average per credit, we divide by the total amount of credits, which is 5 + 3 + 5 + 4 = 17.

Our answer is 49.1/17 = 2.89, rounded to the nearest hundredth
