The answer is 6
3x-12-x-5=2x-11
2x-17=2x-11
=6
Step-by-step explanation:
sums of external angles of triangle =360°
360 - 130 -134
x = 96°
The answer is 27 rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr
You can use the trig ratios. Draw a diagram to see which one is appropriate.
Tan would be used.
Tan29=x/20
20Tan29=x
Put this into your calculator and see what you get
