Answer:

see below

Step-by-step explanation:

-2x + 9 < x − 9

Add 2x to each side

2x-2x + 9 < 2x+x − 9

9 < 3x-9

Add 9 to each side

9+9 < 3x

18 < 3x

Divide each side by 3

18/3 < 3x/3

6 < x

In ΔJKL, the measure of ∠L=90°, JL = 80, KJ = 89, and LK = 39. What is the value of the sine of ∠J to the nearest hundredth

emmainna [20.7K]

Given:

In ΔJKL, m∠L=90°, JL = 80, KJ = 89, and LK = 39.

To find:

The value of sine of ∠J.

Solution:

In a right angle triangle,

$\sin\theta =\dfrac{Perpendicular}{Hypotenuse}$

In triangle JKL,

$\sin J =\dfrac{LK}{KJ}$

$\sin J =\dfrac{39}{89}$

$\sin J =0.4382$

$\sin J \approx 0.44$

Therefore, the value of sine of ∠J is about 0.44.

Answer:

Step-by-step explanation:

a cube has sides of the same length hence its volume is obtain as cubed side.

we have the volume and we need the side:

Log 10 100 =2
Basically, we have to know how to solve for x in this equation:
10^x = 100

For log3 = 9 we have to solve for x in this equation:
3^x = 9
Therefore, x = 2
