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
