x=45°
angle 1=45°
angle 2= 135°
ps are you sure you've written the question properly??
First we find the area of the two triangles on each side (keep in mind that they are equal/congruent to each other):
(24*10)/2 = 120 cm^2
Then you find the areas of the three rectangles that are left:
24*19 = 456 cm^2
26*19 = 494 cm^2
10*19 = 190 cm^2
Finally, to find the surface area of the prism:
120+120+456+494+190 = 1,380 cm^2
3x2+9x-54
6+9x-54
6-54+9x
-48+9x
Right triangle or equilateral(not sure if i spelled it right) triangle
