For this problem, you use tangent, cosine, and/or sine!

Sine is pretty simple in my opinion, so let's use that.
Remember that sine is opposite over hypotenuse, and you're trying to find an angle.

m∠B = sin^-1(4/5)
m∠B = 53.13010...

Your final answer is m∠B = 53 degrees.

$\huge{\red{\boxed{\sf{x = - 6}}}}$

Step By Step Explanation:

Step 1:

→ $4x - 3 = 6x + 9$

Step 2:

→ $4x - 6x = 9 + 3$

Step 3:

→ $- 2x = 12$

Step 4:

→ $x = \frac{12}{ - 2}$

Step 5:

→ $\green{x = - 6}$

verification:

Step 1:

⇝ $4( - 6) - 3 = 6( - 6) + 9$

Step 2:

⇝ $- 24 - 3 = - 36 + 9$

Step 3:

⇝ $- 27 = −27$

Help me!!! I honestly hate number lines..

pentagon [3]

-2.42 goes just before -2.5
-0.8 goes in the middle between -0.5 and -1
0.33 goes between 0 and 0.5
1.23 goes after 1 before 1.5
3/4 = 0.75 which goes in the middle between 0.5 and 1
-2 7/8 goes just before -3

:) Hope that helps :)
