You can use
\frac{1}{2} ab \sin(c)
Since it is an irregular triangle.
C refers to the angle and a & b refer to the adjacent sides.

So,
\frac{1}{2}  \times4.3 \times 3.8 \sin(53)  \\  = 6.52485211 \\  = 6.52

10 yards 1 foot 9 inches divided by 3
AysviL [449]

Answer:

127 inches

Step-by-step explanation:

A single yard is equal to 3 feet. So one yard 1 foot and 9 inches is:

3(10)+1 and 9 inches.

each feet has 12 inches, so it goes something like this:

12(31)+9 inches

multiply it out:

372+9\\381

Thats the total number of inches, now we divide by 3 (use long division:

\frac{381}{3}=127

Hope this helps!

They would be similar triangles because they cannot be congruent due to the fact that the side lengths are different. They are dilutions of each other which again proves that they are similar, not congruent.
