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

Temka [501]
Answer: b, zero

On a graph, when it’s a straight line, there is no slope. When it’s increasing the line, it’s positive, and if it’s decreasing the line, it’s negative, and this line is doing neither.

What’s the solution to -5x-y=21 when y is equal to 6+4x
agasfer [191]

Answer:

x= -3, y=-6

Step-by-step explanation:

In the equation -5x-y=21, substitute y for 6+4x:

-5x- (6+4x) = 21

^^Solve for x.

X should come out to -3. To find y, plug -3 into either equation (-5x-y=21 or y=6+4x) and y should equal -6.
