Law of sines: StartFraction sine (uppercase A) Over a EndFraction = StartFraction sine (uppercase B) Over b EndFraction = StartFraction sine (uppercase C) Over c EndFraction Triangle ABC has measures a = 2, b = 2, and m∠A = 30°. What is the measure of angle B? 15° 30° 45° 60°

Respuesta :

Answer:

30°

Step-by-step explanation:

Law of Sines = [tex]\frac{a}{Sin A} = \frac{b}{Sin B} = \frac{c}{Sin C}[/tex]

[tex]\frac{2}{Sin 30} = \frac{2}{Sin B}[/tex]

[tex]\frac{2}{Sin 30} = \frac{2}{Sin 30}[/tex]

Therefore, m∠B = 30°

Hope that's right and helps

The measure of angle B from the question is; 30°

How to use Law of Sines?

Law of sines states that;

a/sin A = b/sin B = c/sin C

We are given a = 2, b = 2, and m∠A = 30°.  Thus, applying the law of sines, we have;

2/sin 30 = 2/sin B

Cross multiply to get;

B = 30°
