What are the angles of △abc with side lengths a=27, b=11, and c=19?

select the correct answer below:

a=126.2∘, b=19.2∘, and c=34.6∘

a=126.2∘, b=21.2∘, and c=32.6∘

a=126.2∘, b=17.2∘, and c=36.6∘

a=123.2∘, b=19.2∘, and c=37.6∘

The correct answer option is A) A=126.2°, B=19.2°, and C=34.6°.

Step-by-step explanation:

Using cosine rule to find angle A:

Substituting the given values in the formula to get:

A = 126.2°

Now that we have found one angle, we can use sine rule to find the other two angles.

B = 19.2°

C = 34.6°

Therefore, the correct answer option is A) A=126.2°, B=19.2°, and C=34.6°.

x is variable or an unknown value to find
