Find the length of side Y (this is from the geometry for enjoyment and challenge textbook) PLEASE ANSWER ASAP IT'S DUE TOMORROW!
Ymorist [56]

Answer:

y= 3

Step-by-step explanation:

The triangle on the left is a right triangle, so we can use trig functions to solve for the missing side, y.

First, find the length of the side that both triangles are connected to.

tan30=x/9

Isolate the x variable and solve.

9(tan30)=x

x= 5.19615

Now use the Pythagorean Theorem to solve for the side length, y.

a^2+ b^2 = c^2

(5.19615)^2+ b^2= 6^2

c= 3

Suppose that a sequence is defined as follows. This the 1st four terms of the sequence. ASAP BRANLIEST TY!!​
SashulF [63]

Answer:

- 3, 16, - 22, 54

Step-by-step explanation:

Using the recursive formula with a₁ = - 3, then

a₂ = - 2a₁ + 10 = - 2(- 3) + 10 = 6 + 10 = 16

a₃ = - 2a₂ + 10 = - 2(16) + 10 = - 32 + 10 = - 22

a₄ = - 2a₃ + 10 = - 2(- 22) + 10 = 44 + 10 = 54

Thus

the first 4 terms of the sequence are

- 3, 16, - 22, 54

10.5.

Step-by-step explanation:

By similar  triangles:

IJ / 21 = 8 /(8+8) = 1/2

IJ / 21 = 1/2

IJ = 1/2 * 21

= 10.5.
