2 would be the answer. Replace the x with the three and multiply that with the 2 and then subtract 4.
Answer:
8
Step-by-step explanation:
Answer:
exterior angles:
144°and 36°
126° and 54°
90° and 90°
Step-by-step explanation:
we know that each angle in a triangle adds up to 180°.
so,
2x+3x+5x=180
10x=180
x=180/10
x=18
the interior angles are:
2x=36°
3x=54°
5x=90°
and explanation is provided to find the exterior angles above.(sorry for the bad handwriting)
65-14=65-5-x
x=9
Explanation=
65-14=65-5-x
51=60-x
-9=-x
9=x
Answer:
80
