Answer: The length of pencil is 16 centimetres and length of crayons is 8 centimetres
Step-by-step explanation:
Let the length of crayon =
Length of a pencil =
As according to question that the sum of their length is 24 centimetres
So we have

Therefore the length of crayon = 8 centimetres
Length of pencil=
centimetres
Hence, the length of pencil is 16 centimetres and length of crayons is 8 centimetres
Same as the last one ! Review your parallel lines, and you'll see that angles A and B have to be equal. So you solve it EXACTLY the same way as the last one.
You say "A equals B", and that means that
8x - 10 = 3x + 90
Solve that to find x (it's 20),
and then use x to find angle B (it's 150; they both are).
(Don't just take my word for it. Please work it through.)
Answer:
x = 20
Step-by-step explanation:
2x + 7x = 180
⇔ 9x = 180
⇔ x = 180/9 = 20
Let

. Then

Meanwhile, since

, you have

.
It follows that

,

, and

, so that the quadratic fit for

that satisfies the given points is

Note that this is just the second-order Taylor polynomial for

about

.
