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

How do you turn 9 and 3 5s as a decimal???
Zarrin [17]

Answer:

9.6

Step-by-step explanation:

As 9 and 3/5s, the 9 is whole so you do not change it. To make 3/5th into a decimal you increase the denominator into x/10. To make 5 into 10 you multiply 5x2=10. And since you changed the bottom you have to change the top and multiply it by 2. 3x2=6. So the 9 stays the same and since the first place beind the decimal is tenths, and youre fraction is now 6/10 you put it as 9.6.

Hope it helps!
