Triangle abc is a right triangle and cos(22. 6o)=startfraction b over 13 endfraction. Solve for b and round to the nearest whole number. Triangle a b c is shown. Angle a c b is 90 degrees and angle c a b is 22. 6 degrees. The length of hypotenuse a b is 13 centimeters, the length of a c is b, and the length of c b is a. Which equation correctly uses the value of b to solve for a?.

The smokey mountains have over 2,100 miles of rushing mountain streams and rivers that flow through the park. in each mile lives a diverse community of native fish, amphibians, insects, and larvae, some of which are found only in the southern appalachians. park managers and scientific researchers test many factors such as fish populations, the watersheds and water tests to determine a) too many lizards are present b) the water quality of the stream c) rainwater is running into local streams d) if visitors to the park are overstaying their welcome
