Draw a cartesian graph and draw the points in , then see where c should be to get a right angled triangle
top four are yes yes no yes
Answer:
Step-by-step explanation:
0.5cos(2pi/9x-7pi/9)-4.5
There’s probably an easier way to do it like with the equation to find the area of a trapezoid but i did it this way bc it’s easier for me
i split the trapezoid into a triangle and a square
with the pythagorean theorem i found the missing side length to find the area of the square (length X width)
then found the area of the triangle (base X height divided by 2)
THE ANSWER IS 68.9 CM
