If you don't double check your answers by substituting them back into the original equation, you may be introducing extraneous solutions into the problem which is why you should always check to confirm your answer is accurate. I hope this helps! :)

Solve the triangle. A = 19°, C = 102°, c = 6
GrogVix [38]
We know that

Law of sines established
a/sin A=b/sin B=c/sin C

then
a/sin A=c/sin C------------> a=c*sin A/sin C---------> a=6*sin 19/sin 102
a=1.91 units <span>≈2 units

A+B+C=180</span>°----------> B=180-(A+C)-----> B=1180-(19+102)
B=59°
a/sin A=b/sin B-----------> b=a*sin B/sin A----->2*sin 59/sin 19
b=5.27 units <span>≈5.3 units</span>

the answer is the option 
B = 59°, a ≈ 2, b ≈ 5.3

A bulletin board can be covered completely by 30 square pieces of paper without any gaps or overlaps if each piece of paper has
34kurt

Answer:

The area of the bulletin board is 30 square foot.

Step-by-step explanation:

A bulletin board can be covered completely by 30 square pieces of paper without any gaps or overlaps.

If each piece of paper has side length of 1 foot so the area of each paper is 1 ft x 1 ft = 1 square foot.

There are 30 pieces of paper needed to completely cover the bulletin board, so 30 pcs of paper with an area of 1 square foot is equal to 30 square feet. The area of the bulletin board is 30 square foot.
