Answer:

2 km

Step-by-step explanation:

Reference angle = 45°

Opposite = u

Hypotenuse = 2√2 km

To find u, apply SOH:

Sin 45° = Opp/Hyp

Sin 45° = u/2√2

√2/2 = u/2√2 (sin 45 = √2/2)

Cross multiply

2*u = √2*2√2

2u = 4

Divide both sides by 2

u = 4/2

u = 2 km

ANSWER RIGHT FOR BRAINLIEST PLEASE equation of the line that passes through the point (–2, 3) and has a slope of 1/3

morpeh [17]

Answer:

y = $\frac{1}{3}$ x + $\frac{11}{3}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = $\frac{1}{3}$ , thus

y = $\frac{1}{3}$ x + c ← is the partial equation

To find c substitute (- 2, 3) into the partial equation

3 = - $\frac{2}{3}$ + c ⇒ c = 3 + $\frac{2}{3}$ = $\frac{11}{3}$

y = $\frac{1}{3}$ x + $\frac{11}{3}$ ← equation of line

Solve the following inequality: x+5≤(−x+2)+x

vesna_86 [32]

Answer:

<h2>x ≤ - 3</h2>

Step-by-step explanation:

x + 5 ≤ ( - x + 2) + x

<u>Remove the parenthesis</u>

That's

x + 5 ≤ - x + 2 + x

x + 5 ≤ 2

Using the subtraction property subtract 5 from both sides

That's

x + 5 - 5 ≤ 2 - 5

x ≤ 2 - 5

We have the final answer as

<h3>x ≤ - 3</h3>

Hope this helps you
