Use a projector. Great. Then solve 3 · y and 5 · x + 2. Don't know how to use the projector? There's videos about it, but I'll teach you. Your projector has a hole. Mark the point of the vertex..
Wait, I don't know how to explain this.. Now let's pretend that you already have measured the angles. Now you might should divide it. C [divided by] 3 = y. For D, it'll be a little different. D [divided by] 5 - 2 = x. (Sorry can't make a division sign my keyboard doesn't have it) Now that's your answer(s). Bye.
Use Pythagorean theorem to solve. a^2 + b^2 = c^2 6^2 + b ^2 = 14^2 36 + b^2 = 196 Subtract 36 from both sides. b^2 = 196-36 b^2 = 160 Take the square root of both sides. b = sqrt 160 As a decimal b = 12.649 As a simplified radical b = 4sqrt10
