Given: abc is a right triangle with right angle c. ab=18 centimeters and m∠a=22∘ .what is bc ? enter your answer, rounded to the nearest tenth, in the box.

6.7cm

Step-by-step explanation: I took the K12 test.

BC = 6.7 cm (rounded to nearest tenth)

Explanation:

Given: ABC is a right triangle with right angle C as shown below.

Side AB=18 cm and m∠A=22°.

Using Sine ratio in triangle ABC to find BC.

Sine ratio is defined as the ratio of the opposite side of a right triangle to the hypotenuse.

i.e

Let BC = x (opposite side) and AB = 18 cm(Hypotenuse side)

then;

Multiply both sides by 18 we get;

therefore, value of BC (nearest tenth place) is, 6.7 cm

step-by-step explanation:

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
