Solving for a missing side.
Find the missing side. Round to the nearest tenth. Please show the work. Part 1

1. 26.6

2. 12.3

3. 23.3

4. 10.9

Step-by-step explanation:

1. tan(31) = 16/x

x = 16/tan(31)

x = 26.62847172

2. sin(43) = x/18

x = 18sin(43)

x = 12.27597048

3. cos(53) = 14/x

x = 14/cos(53)

x = 23.26296198

4. cos(33) = x/13

x = 13cos(33)

x = 10.90271738

1. 26.6 units

2. 12.3 units

3. 23.3 units

4. 10.9 units

Step-by-step explanation:

1. We have the opposite and adjacent sides here for angle 31 degrees. So we need to use tangent, which is opposite / adjacent:

≈ 26.6 units

2. We have the opposite and hypotenuse sides here for angle 43 degrees. So we need to use sine, which is opposite / hypotenuse:

≈ 12.3 units

3. We have the adjacent and hypotenuse sides here for angle 53 degrees. So we need to use cosine, which is adjacent / hypotenuse:

≈ 23.3 units

4. We have the adjacent and hypotenuse sides here for angle 33 degrees. So we need to use cosine, which is adjacent / hypotenuse:

≈ 10.9 units
