1. consider one angle of a (convex) heptagon. From that angle you can construct 7-3=4 diagonals. (-3 because we cannot create diagonals with the adjacent vertices and the angle itself )
2. 4 diagonals create 5 triangular regions. (check the picture)
3. So the sum of the measures of the interior angles of the heptagon is 180°*5=900°.
4. The measure of the remaining 7th interior angle is 900°-(120+150+135+170+90+125)°=110°.
5. The largest exterior angle is when the interior angle is the smallest.
6. The smallest interior angle is 90°, so the largest exterior angle is 180°-90°=90°
Answer: 90°
It is increase, because 15 is less than 18. Other way around, if the question is 18 to 15 yards, then that would be decrease, because it is getting smaller.
Answer:
c squared - a squared = b squared
Step-by-step explanation:
Since a squared + b squared = c squared
With these values it would equal 14 squared - 7 squared = c squared
Then after you find c squared, find the square root of it and there you have go your answer!
Answer:
Actual length = 36
Step-by-step explanation:
<u>0.5 inches</u> = <u>12 inches</u>
1.5 = x
0.5x = 18 Solve for x
x = 36
I hope this helped and please mark me as brainliest!
Answer:
200 rounded to the nearest hundredth
Step-by-step explanation:
Acute is about 30 degrees so 30+30=60
so a right angle is 90 degrees right so 90 + 60 =150 round it to the nearest hundredth and you have 200 that's how i got my answer :))
