They are COMPLEMENTARY ANGLES since they form a right angle or add up to 90°
To estimate you would round the numbers, so it would be 7,000 - 4,000 = 3,000.
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)
If you're simplifying, you would get -258 I believe.
Answer:
yes
Step-by-step explanation:
40% of 16 = 6.4
16% of 40 = 6.4
