Polyhedron 2: Solid:___Octahedron__ Number: __1___
Solid:__Tetrahedron___ Number: __8___
Complement of an alngle means what you need to add to it to make 90 degrees
comlement of angle x is y such that x+y=90
so if complement of angle x is 25, that means the angle x is found by
x+25=90
minus 25 both sides
x=65 degrees
the angle measures 65 degree
Answer:
12 miles
Step-by-step explanation:
19 - 4 = 15
15/1.25 = 12
Answer:
B
Step-by-step explanation:
X is the domain.
The function comes from -∞ and goes to ∞
So B is the answer.
Answer:
Step-by-step explanation:
Solving for x. Want to solve for f instead?
Step 1 move all terms to one side
fx - 4x² + 100 =0
Step 2 Use the Quadratic Formula
x = -f + √f² + 1600 ÷ -8, -f-√f²+1600 ÷ -8
Done.
