Use these measurements to find the length of the tunnel. 2 209 m 82° 151 m Carry your intermediate computations to at least four decimal places. Round your answer to the nearest tenth of a meter. meters X C

The cross section of a dovetail slide is shown. Before the dovetail was cut, the cross section was rectangular in shape. Find the cross-sectional area of the dovetail slide. Round the answer to 1 decimal place.

Determine the length of side b. Round the answer to 3 decimal places.

The length, L, of the standard 82° included angle drill can be calculated using the formula L=0.575 , where Ø represents the diameter of the drill. Determine the length of a drill point with a diameter of 12.5 mm. Round your answer to 1 decimal place.

Use the Distance Formula to find the distance between the points (4,5) and (3,4). Write the answer in exact form and then find the decimal approximation, rounded to the nearest tenth if needed.

Determine the size of x to the nearest hundredth degree.
