$9x+14=2x+35 \\ \\ 9x + 14 - 2x = 2x + 35 - 2x \\ \\ 7x + 14 = 35 \\ \\ 7x + 14 - 14 = 35 - 14 \\ \\ 7x = 21 \\ \\ \frac{7x}{7} = \frac{21}{7} \\ \\ \huge{x = 3 }$

I don’t understand this

Dahasolnce [82]

Answer:

Yes

Step-by-step explanation:

Statement 1: If JK and LM bisect each other then, they divide each other in 2 equal parts.

So,

JP = PK [Because of statement 1]

MP = PL [Because of statement 1]

∠JPM = ∠LPK [Because they are vertically opposite angles]

So, ΔJPM ≅ to ΔKPL [By SAS congruence criteria of triangle]

Proportions in similar triangles

Svetradugi [14.3K]

Answer:

x = 4

Step-by-step explanation:

Given that DE is parallel to AC then DE divides the sides proportionally, so

$\frac{BD}{DA}$ = $\frac{BE}{EC}$ , substitute values

$\frac{x+2}{x}$ = $\frac{3}{2}$ ( cross- multiply )

3x = 2(x + 2) ← distribute

3x = 2x + 4 ( subtract 2x from both sides )

x = 4

How long is the arc intersected by a central angle of StartFraction 5 pi Over 3 EndFraction radians in a circle with a radius of

qaws [65]

The length of the arc of the circle with a radius of 2 ft and the angle made at the centre equal to $\dfrac{5\pi}{3}$ is 10.5ft.

<h3>What is the length of the arc of a circle?</h3>

The length of the arc of a circle is equal to the product of the circumference of the circle and the ratio of the angle made by the arc of the circle to 2π. It is given by the formula,

$\text{Length of the arc}= 2\pi r\times \dfrac{\theta}{2\pi}$

It is given that the radius of the circle is equal to 2 ft while the angle made by the arc at the centre of the circle is equal to $\dfrac{5\pi}{3}$ . And we know the formula for the length of the arc, therefore, the length of the arc,

$\text{Length of the arc}= 2\pi r\times \dfrac{\theta}{2\pi}$

$= 2\pi \times 2 \times \dfrac{\frac{5\pi}{3}}{2\pi}\\\\= 10.471 \approx 10.5\rm\ ft$

Hence, the length of the arc of the circle with a radius of 2 ft and the angle made at the centre equal to $\dfrac{5\pi}{3}$ is 10.5ft.
