Answer:

17.1 degrees

Step-by-step explanation:

This is a tangent question because angle XYZ is adjacent to 13 and opposite of 4. This means that we will have to use opposite/adjacent. This is very simple if you know the formula. Just plug those numbers in to get 4/13 = 0.3076923076923077. However, now we need to find it in degrees. If you have an inverse calculator near you, you would plug it in to get about 17.10, which rounds to 17.1.

Answer:

<h2>73°</h2>

Step-by-step explanation:

Opposite = 13cm\\Adjacent = 4cm\\\alpha =?\\Using SOHCAHTOA ;\\Tan \alpha = \frac{opp}{adj} \\Tan \alpha =\frac{13}{4} \\\alpha =Tan^-^1=\frac{13}{4} \\\alpha = 72.89\\=73\°

For this case we can model the problem as a rectangle triangle.
 We know:
 Length of the sides of the triangle
 We want to know:
 Length of the hypotenuse
 Using the Pythagorean theorem we have:
 d =  \sqrt{3^2 + 3^2}
 Rewriting the expression we have:
 d = \sqrt{2(3^2)}
 d = 3\sqrt{2}
 d = 4.2 miles
 Then, the distance that he would have saved if he travels directly is:
 3 + 3 - 4.2 = 1.8 miles&#10;
 Answer:
 
he would have saved:
 
1.8 miles
