Answer:

By Pythagoras theorem, we get

{x}^{2}  +  {x}^{2}  =  {( \sqrt{72}) }^{2} \\ 2 {x}^{2}  =  72 \\  {x}^{2}  = 36 \\  \boxed{x = 6}

<h2>C) <u>6 inches</u> is the right answer.</h2>

Answer:

C)  6 inches

Step-by-step explanation:

(√72)² = x² + x²

72 = 2x²

72/2 = x²

36 = x²

√36 = √x²

6 = x

x = 6 inches

1). y-3=-2(x+4)

2) slope = 3/4
y+2=3/4(x+4)
y=3/4x +1

What value of x is in the solution set of 2x – 3 &gt; 11 – 5x?
pochemuha

Given:

2x -3 > 11 -5x

Simplify both sides:

2x - 3 > -5x + 11

Add 5x to both sides:

2x - 3 +5x > -5x + 11 +5

7x - 3 > 11

Add 3 to both sides:

7x - 3 +3 > 11 + 3

7x > 14

Divided 7 to both sides:

\frac{7x}{7} > \frac{14}{7}

x > 2

I need help! I don't know how to get the answer or what it is. Can anyone help me it's for a test and I'm on my last attempt?
Greeley [361]

Answer:

See explanation

Step-by-step explanation:

(4)

Using the sine ratio in  the right triangle

sinΘ = \frac{opposite}{hypotenuse} = \frac{7}{9}, thus

Θ = sin^{-1}(\frac{7}{9}) ≈ 51.1°

(5)

Using the tangent ratio in the right triangle

tanΘ = \frac{opposite}{adjacent} = \frac{4}{5}, thus

Θ = tan^{-1}(\frac{4}{5}) ≈ 38.7°
