Question

Find values of x,y,z in the triangle

Answer 1

That's an equilateral triangle since the three interior angles are congruent. So angle x =60 degrees; angle y = 60 degrees and angle z =60 degrees.

If you want to know the value of x in the expression 3x+6, note there is 180 degree in a straight line.

So the sum angle y and angle (3x +6) equals 180 degrees.

60 + (3x +6)= 180
3x+6=120
3x=114
x=38


If you take the sum of angle z and (3x-6) equals 180 degrees
60+(3x-6)=180
3x-6=120
3x=126
x=42

Will the real value of x please stand up! Clearly there is a problem with the labeling.
