3 (y + 10) + 2y - 5 = 0
3y + 30 + 2y - 5 = 0
1y + 30 - 5 = 0
1y + 25 = 0
1y = -25
y = -25

The area of triangle ABC is 24 square centimeters. If B = 30° and a = 6 cm, what is the measure of side c? 4 cm 8 cm 16 cm 32 cm
disa [49]

Answer:

16 cm

Step-by-step explanation:

Given : The area of triangle ABC is 24 square centimeters.

To Find: If B = 30° and a = 6 cm, what is the measure of side c?

Solution:

Formula : Area = \frac{1}{2} \times a \times c \times sin B

a = 6

Area = 24

B = 30°

Substitute the values in the formula

24 = \frac{1}{2} \times 6 \times c \times sin 30

24 = \frac{1}{2} \times 6 \times c \times \frac{1}{2}

24 =3 \times c \times \frac{1}{2}

\frac{24 \times 2}{3} =c

16=c

Hence the measure of side c is 16 cm

So, Option c is correct.
