What is the volume of a square pyramid whose length of one side of its base is 9cm and whose height is 15cm. Show your work

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet

2: 10

step-by-step explanation:

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140
