Step-by-step explanation:
Answer:
See below.
Step-by-step explanation:
X-intercepts: (-7, 0) & (-3, 0)
Axis of Symmetry: x = -5
Y-intercept: (0, -21)
Vertex: (-5, 4)
Cosine(angle) = adjacent leg/ hypotenuse
Cosine( angle ) = 18/20
Angle = arccos(18/20)
Angle = 26 degrees
<u>Answer:</u>
<h2>SA = 84 ft²</h2>
<u>Explanation:</u>
SA = the area of one side of the pyramid times 4 + the area of the base of the pyramid
Area of a triangle = (height × base)/2
Area of a sqaure = lenght²
given:
h = 4 ft | b = 6 ft | l = 6 ft
SA = 4(h×b×1/2) + l²
SA = 4(4×6×1/2) + 6²
SA = 4×12 + 36
SA = 48 + 36
SA = 84 ft²
