Answer:
7.1
Step-by-step explanation:
Once again we can use trig ratios to solve for ST
First we must recall the trig function
Sin = Opposite over Hypotenuse
Cos = Adjacent over Hypotenuse
Tan = Opposite over Adjacent
We are given the measure of an angle and the length of the hypotenuse
Of the given angle we need to find the adjacent side length
When working with the hypotenuse and adjacent we use trig function cosine
That being said we want to create an equation ( remember cos = adjacent over hypotenuse ) ( let ST = x)
now we solve for x
Step 1 multiply each side by 9.5
we're left with x = 7.059875842
Finally we round to the nearest tenth and get that the answer is 7.1
