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

Answer:

The first step is A. Subtraction

The second steep is D. Division

Step-by-step explanation:

The first step was done in other to remove the constant at one end of the equality that was with the variable, it was done in order to eradicate the constant and isolate the variable to make the equation easier to solve.

The second step was done in order to remove the coefficient of the variable so as the variable to be on it's own as x alone.

These two steps were just followed in order to find the value of the variable.

How do i do this?????????
Gnom [1K]

Answer:

x≥5

Step-by-step explanation:

-1 ≥ x/-5

x/-5 ≤ -1

x(-1)/5 ≥ (-1) (-1)

x/5 ≥ 1

5x/5 ≥ 1 ×5

x ≥ 5

I'm not sure but I tried.

For the graph: you can draw a line about 15cm, put 0 at the start then after 5cm put 5 then 10 at 10cm and 15 at the end. At 5 put • that's the starting and go all the way to 15 and add > to show that the line continues. I'm not good at explaining but I hope it helps.
