Hatshy [7]

Answer:

1. 29.67°

2. 68.96°

3. 89.85°

Step-by-step explanation:

1. Reference angle = x

Opposite = 45 cm

Adjacent = 79 cm

Therefore:

tan(x) = \frac{45}{79}

tan(x) = 0.569620253

x = tan^{-1}(0.569620253)

x = 29.67 (nearest hundredth)

2. Reference angle = B

Opposite = 14

Hypotenuse = 15

Therefore:

sin(B) = \frac{14}{15}

sin(B) = 0.93333

B = sin^{-1}(0.93333)

B = 68.96 (nearest hundredth)

3. Reference angle = x

Adjacent = 238,900 mi

Hypotenuse = 92,955,807 mi

Therefore:

cos(x) = \frac{238,900}{92,955,807}

x = cos^{-1}(\frac{238,900}{92,955,807})

x = 89.85 (nearest hundredth)
