MHB Finding the Measures of Angles in a Linear Pair

AI Thread Summary
In a linear pair, the measures of two angles sum to 180 degrees. Given m<1 = 5x + 9 and m<2 = 3x + 11, the equation to solve is 5x + 9 + 3x + 11 = 180. Solving for x allows for the determination of the individual angle measures. Understanding the concept of a linear pair is crucial for setting up the equation correctly. The problem emphasizes the importance of recognizing angle relationships in geometry.

<1 and <2 form a linear pair. If m<1 = 5x + 9 and m<2 = 3x + 11, find the measures of both angles.

Hi bernardl and welcome to MHB! :D

I've re-titled your recent threads to give them a name that accurately reflects the problem at hand.

A linear pair of angles have measures that sum to 180 degrees, so we want to solve

5x + 9 + 3x + 11 = 180

for x, then substitute that value for x into the respective expressions to find the measure of the two angles.
 
Whoever gave you this problem clearly expected you to know what "linear pair of angles" meant! Did you? If so it is easy to set up an equation to solve.
 

Thread 'Trigonometry problem of interest'

Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...

Thread 'Six Pencil Puzzle'

Is it possible to arrange six pencils such that each one touches the other five? If so, how? This is an adaption of a Martin Gardner puzzle only I changed it from cigarettes to pencils and left out the clues because PF folks don’t need clues. From the book “My Best Mathematical and Logic Puzzles”. Dover, 1994.

Thread 'Imaginary Pythagoras'

I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
