Answer: x = 12</h3>
Explanation:
The two angles shown are vertical angles. This occurs whenever you have an X shape like this, and whenever the angles are opposite one another. Vertical angles are always congruent.
6x+7 = 8x-17
6x-8x = -17-7
-2x = -24
x = -24/(-2)
x = 12
Remember SOHCAHTOA
Sine- opposite/hypotenuse
Cosine- adjacent/hypotenuse
Tangent- opposite/adjacent
Look at the angle (x) you are trying to figure out and pick which one of these it is.
In your calculator, do the equation first to get a decimal
Then press whichever one you chose on the calculator, so if you got like 0.2 by doing opposite/adjacent for tangent, you would type in 0.2 and then the TAN button
hope this makes sense!!
Step-by-step explanation:
AC = AB + BC
25x - 19 = 9x + 7 + 5x + 7
25x - 19 = 14x + 14
25x - 14x = 14 + 19
11x = 33
x = 33/11
x = 3
AB = 9x + 7
= 9(3) + 7
= 27 + 7
= 34
Answer:
You can buy 6 tickets.
Step-by-step explanation:
21.8 + 26.6 = 48.4
48.4 x 2.50 = 121
121 / 17.50 = 6.914
Since we can't round here because it's items you're buying, we round down to the nearest flat number, which in this case is 6.
