The frigate bird has a top recorded speed of 153 kilometers per hour. How would you state this speed in the appropriate customary unit? (1 km = 0.62 mi)

94.86 miles per hour

Step-by-step explanation:

The frigate bird has a top recorded speed of 153 kilometers per hour. How would you state this speed in the appropriate customary unit? (1 km = 0.62 mi)

The appropriate customary unit is calculated as:

1 km = 0.62 miles

153 km = x

Cross Multiply

x = 153 × 0.62 miles

94.86 miles

Therefore, the appropriate customary unit is 94.86 miles per hour

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
