Answer:
3
Step-by-step explanation:
15 - 2(7 - x) = 7
collect like terms
-2(7 - x) = 7 - 15
-2(7 - x) = -8
divide both sides by -2
7 - x = -8/-2
7 - x = 4
collect like terns
-x = 4 - 7
-x = -3
dividing both sides by -
x = 3
Hi there!
Since you haven't given any numbers, I'll explain what you can do to figure this problem out. First, determine what side you have in relation to the angle (is it adjacent to the angle, it is opposite the angle, is it the hypotenuse?). Then, determine which trigonometry function to use (Sine = opposite/hypotenuse, Cosine = adjacent/hypotenuse, Tangent = opposite/adjacent). Check out the image below if you're confused. Anyway, you can use trigonometry to find the missing side of a triangle when only given angles and a side. All you have to do is plug in the numbers given and solve. (In the image, the O with a line through it represents the angle measurement that will be plugged in there.)
Hope this helps!! :)
If you're still confused or would like help solving a trigonometry problem, feel free to send me a message!
