Accepted Solution

A:
Answer:The length of side BC is 20.5 inStep-by-step explanation:we know thatIn the right triangle ABCThe function cosine of angle of 35 degrees is equal to divide the adjacent side to angle of 35 degrees by the hypotenuse of the right trianglesocos(35°)=a/25Solve for aMultiply by 25 both sidesa=(25)*cos(35°)=20.5 inthereforeThe length of side BC is 20.5 in
