Answer:
x ≈ 65.4 °
Step-by-step explanation:
cos x = 
Cos x = 
Cos x = 0.4167
x = Cos⁻¹ (0.1467)
x ≈ 65.4 °
I say that it is A because I did this did this before
Both of this angles are same side interior angles which means both of this angles when added equal to 180 degrees
5x +15 + 3x - 3 = 180
8x - 12 = 180
+12 +12
8x = 192
x = 24
<h2>1.</h2>
Firstly, combine like terms: 
Next, subtract r on both sides of the equation: 
Next, add 8 onto both sides of the equation: 
Lastly, divide both sides by 6 and <em><u>your answer will be r = 3.</u></em>
<h2>2.</h2>
Firstly, multiply both sides by e: 
Lastly, divide both sides by 3, and <em><u>your answer will be
</u></em>
