Since this is a right triangle, we can use one of the three main trigonometric functions: sine, cosine, or tangent.

Remember: SOH-CAH-TOA

Looking from angle I, we know the opposite side and the hypotenuse. Therefore, we should use sine.

sin(I) = $\frac{\sqrt{39}}{\sqrt{51}}$

To solve, you can use your calculator and the inverse sine function (sin^-1).

I = sin^-1( $\frac{\sqrt{39}}{\sqrt{51}}$ )

I = 61 degrees

Hope this helps!

A delivery truck drives three routes in one day. The first route is 1223 miles long, the second route is 1034 miles long, and th

avanturin [10]

Answer:

$Total = 38\frac{11}{12}\ miles$

Step-by-step explanation:

Given

$First\ Route = 12\frac{2}{3}\ miles$

$Second\ Route = 10\frac{3}{4}\ miles$

$Third\ Route = 15\frac{1}{2}\ miles$

Required

Determine the total miles

$Total = First\ Route + Second\ Route + Third\ Route$

$Total = 12\frac{2}{3} + 10\frac{3}{4} + 15\frac{1}{2}$

Convert to improper fractions

$Total = \frac{38}{3} + \frac{43}{4} + \frac{31}{2}$

Take LCM

$Total = \frac{152 + 129 + 186}{12}$

$Total = \frac{467}{12}$

$Total = 38\frac{11}{12}\ miles$
