Step-by-step explanation:
The two like fractions can be set as x and y (just to use two variables).
One of them is , though, so we can set one of the variables equal to that value (I'm just going to make , it doesn't matter which variable you use).
We also know that adding the two variables gives us so now we can make an equation.
Answer:
sec A = sqrt(61) / 6
sec theta = hypotenuse / adjacent side
72
You need to add the two middle numbers then divide them by two.
Hope this helps.
