Answer:
11.8° and 78.2°
Step-by-step explanation:
let the angles be x and x + 66.4
complementary angles sum to 90° , then
x + x + 66.4 = 90
2x + 66.4 = 90 ( subtract 66.4 from both sides )
2x = 23.6 ( divide both sides by 2 )
x = 11.8 and
x + 66.4 = 11.8 + 66.4 = 78.2
The 2 angles are 11.8° and 78.2°
V pyramid = (1/3)*B*h where B is the area of the base
V = (1/3) * 12 * 16 * 7
V = 448 m^3
Answer:
The answer is D (line symmetry and rotational symmetry; 180o; order 2.
Step-by-step explanation:
You can fold the figure in half and it would be the same on both sides. The figure also has rotational symmetry because if you rotate the figure 180 degrees about the center, then it basically maps itself, or in other words, its the same. So the ANSWER IS D
