The error is that the graph is moving up two and over one. Basically using the slop 2/1 instead of 1/2. The slope is rise/run, so it should rise up 1 unit and run 2 units to the right.
Answer:
w = 10 cm
Step-by-step explanation:
The area of the triangle is 24 sq. cm.
24 * 5 = 105
120/12 = 10
40/50 is the ratio because the cos formula is adjacent over hypotenuse and you can reduce it to 4/5 as a fraction :)
2x3x5=30
3 is from the amount of sides in the triangle
