Answer:
27 degrees and 63 degrees
Step-by-step explanation:
Let n be the number.
Angle 1: 2n-15
Angle 2: 3n
If the angles are complementary they add up to 90.
Therefore we can write an equation.
2n-15+3n=90
Combine like terms
5n-15=90
Add 15 to both sides
5n=105
n=21
Now we plug 21 in for n and solve for the angles
Angle 1 = 2(21)-15
Angle 1 = 42-15
Angle 1 = 27
Angle 2 = 3(21)
Angle 2 = 63
Answer:
Step-by-step explanation:
3 rows of 21 sneakers.
If you add 21+21 it equals 42, which is two rows. If you add that last row, 42+21, you end up with 63.
Hello, i definitely don’t know i just need to answer something sorry
Answer:
A, 152 cm.
Step-by-step explanation:
A rectangular pyramid has a volume equation of
V = (lwh)/3.
Therefore, when we plug the values in:
[(7)(5)(13)]/3 = V
V = 455/3
V = 151.666667
V is approximately equal to 152 cm^3.
I hope this helped! :)
