X/-9 =3<br>I dont understand this.

STatiana [176]

Final Answer: $x = -27$

Steps/Equations:

Question: $\frac{x}{-9} = 3$

Step 1: Move the negative sign to the left side.

$-\frac{x}{9} = 3$

Step 2: Multiply both sides by $3$ .

$-x = 3 * 9$

Step 3: Simplify $3 * 9$ to $27$ .

$-x = 27$

Step 4: Multiply both sides by $-1$ .

$x = -27$

PLEASE HELP ASAP ILL GIVE BRAINLIEST!!!!!<br><br>find measure of arc MK

Gwar [14]

Answer:

Arc length MK = 15.45 units (nearest hundredth)

Arc measure = 58.24°

Step-by-step explanation:

Calculate the measure of the angle KLN (as this equals m∠KLM which is the measure of arc MK)

ΔKNL is a right triangle, so we can use the cos trig ratio to find ∠KLM:

$\sf \cos(\theta)=\dfrac{A}{H}$

where:

$\theta$ is the angle
A is the side adjacent the angle
H is the hypotenuse (the side opposite the right angle)

Given:

$\theta$ = ∠KLM
A = LN = 8
H = KL = 15.2

$\implies \sf \cos(KLM)=\dfrac{8}{15.2}$

$\implies \sf \angle KLM=\cos^{-1}\left(\dfrac{8}{15.2}\right)$

$\implies \sf \angle KLM=58.24313614^{\circ}$

Therefore, the measure of arc MK = 58.24° (nearest hundredth)

$\textsf{Arc length}=2 \pi r\left(\dfrac{\theta}{360^{\circ}}\right) \quad \textsf{(where r is the radius and}\:\theta\:{\textsf{is the angle)}$

Given:

r = 15.2
∠KLM = 58.24313614°

$\implies \textsf{Arc length MK}=2 \pi (15.2)\left(\dfrac{\sf \angle KLM}{360^{\circ}}\right)$

$\implies \textsf{Arc length MK}=\sf 15.45132428\:units$

If f(x) = 8, what is f(x) when x = 10?

poizon [28]

F(x) = 8.

This is a constant function. No matter the value of x, f(x) will always be = 8

Therefore when x = 10, f(x) = 8.

The difference of two complementary angles is 20. Find the measure of each angle

stich3 [128]

Answer:

35° , 55°

Step-by-step explanation:

Let one angle be x.

It's complementary angle is = (90 - x)°

According to the question ,

$x - (90 - x) = 20$

$=> x - 90 + x = 20$

$=> 2x = 90 - 20 = 70$

$=> x = \frac{70}{2} = 35$
