a² + b² = c²

6² + b² = 10²

36 + b² = 100

100 - 36 = 64

√64 = 8

x = 8

Just use the Pythagorean theory. a^2 + b^2 = c^2

Plug in the values appropriately.

6^2 + b^2 = 10^2

36 + b^2 = 100

b^2 = 64

b = sqr root 64

b = 8

Therefore

x = 8

BRAINLIEST. NEED HELP NOW!!!<br> What is the value of x?

Arturiano [62]

Answer:

x=10

Step-by-step explanation:

these are similar triangles

8 12

------ = -----------

x+4 2x+1

using cross products

8* (2x+1) = 12(x+4)

distribute

16x + 8 = 12x+48

subtract 12x from each side

16x-12x +8 = 12x-12x+48

4x+8 = 48

subtract 8 from each side

4x+8-8 = 48-8

4x = 40

divide by 4

4x/4 = 40/x

x =10

Find the value of questions

Zolol [24]

Answer:

The simplified expression is:

$\frac{3^9y}{2\times \:81}=\frac{243y}{2}$

Step-by-step explanation:

Given the expression

$\frac{3^9\times \:y}{2\times 81}$

solving the expression

$\frac{3^9\times \:y}{2\times 81}=\frac{3^9y}{162}$

$=\frac{3^9y}{3^4\times \:2}$ ∵ $162=3^4\times \:2$

$=\frac{3^5y}{2}$ ∵ $\mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}=x^{a-b}$

$=\frac{243y}{2}$ ∵ $3^5=243$

Therefore, the simplified expression is:

$\frac{3^9y}{2\times \:81}=\frac{243y}{2}$
