Answer:

Step-by-step explanation:
Hello,

I think it's just determining what the negative means. Negative with the x axis means to the left (because the left side is negative). Negative with the y axis is down (because the down side is negative.) So once you know that, it's obviously D because both are negative.
I hope that helped!

Area of triangle = (1/2)*b*h = (1/2)*7*10
= 7*5 = 35 squared cm
The measurement of Angle 1 is 61 degrees.
The diagram shows how the surface area can be "flattened" into two rectangles, one for the end triangles that is 6 cm by 5.3 cm, and one for the lateral area that is 13 cm by 19.3 cm.
The total area is
.. (6 cm)*(5.3 cm) +(13 cm)*(19.3 cm)
.. = 31.8 cm^2 +250.9 cm^2
.. = 282.7 cm^2
