If alc and ab = c, prove that alb

Mathematics
1 answer:
balandron [24]3 years ago

Answer:

This isn't true.

Step-by-step explanation:

Think of the case a=2, b=3 and c=6. We have that a|b, since 2|6.

We also have that ab=c, since 2*3=6. However, it is NOT true that a|b, as 2 does NOT divide 3. As this you can construct many other examples where a|c and ab=c BUT a does NOT divide b.

Other counterexamples:

a=2, b=5, c=10

a=2, b=7, c=14

a=2, b=11, c=22

a=2, b=13, c=26

Answer:

Adjacent angles and not a linear pair

Step-by-step explanation:

They are adjacent because they are located right next to each other and share a common side.  They aren't linear because both angles don't sit on a straight line by themselves.  <DGB is also on that line; therefore, <AGE and <EGD and <DGB would add up to 180 degrees.

The length of the leach is 16.05 ft and the area of the mainsail is 64.94 ft²

<h3>What is application of law of sines?</h3>

The law of sines refers to the ratio of side length of triangle to the sine of the opposite angle which is same for all the sides.

SinA / a = SinB/ b = SinC/c

where, the A,B,C are the angles of the triangle and a,b,c are the opposite sides of the angle of triangle.

The mainsail foot is 13 feet long, the luff is 10 feet long has the length of the leach 6.93 ft and the area of the mainsail is 64.85 .

Part A; By using the law of sines;

SinA /10 = SinB / 13

SinA /10 = Sin54 / 13

A = 38.49°

C = 180 - (54 + 38.49)

C = 87.51°

So, Sin38.49 / a = Sin54/ b = Sin87.51/c

Sin38.49 / 10 = Sin54/ 13 = Sin87.51/c

c = Sin87.51 × 13 ÷ Sin54

c = 16.05 ft

Part B; Area of the mainsail = 1/2 × ab SinC

Area = 1/2 × 10 × 13 × Sin87.51

Area =  64.94 ft

Therefore, the length of the leach is 16.05 ft and the area of the mainsail is 64.94 ft²
