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!
Since b1 stand for base 1 you should find the base and plug in the numbers there’s parentheses so you solve this first so you’d solve _+_=_ usually theres a line going straight with a number around it that’s gonna be your height and your other 2 are the bases
Factor the gcf
3x(x^2-8x+12)
Then factor the inner trinomial
3x(x-6)(x-2)
Final answer: 3x(x-6)(x-2)
Answer is 12.50. u can comment on my answer if you would like to see how that is the correct answer :)
