The sum of the interior angles of a pentagon is 540 degrees. We find the measure of the fifth angle by summing up the four angles given and subtracting this to the total sum. We calculate as follows:
Fifth angle = 540 - (40+80+115+165) = 140 degrees
Hope this answers the question.
Answer:
45 points in round 3
Step-by-step explanation:
x + 30 + 25 = 100
combine like terms
30+25 = 55
x + 55 = 100
- 55 - 55
--------------------
x = 45
therefore, Amos scored 45 points in round 3
hope this helps! :D
have a MIRACULOUS day, and brainliest is immensely appreciated!! <3
Answer:
Y=-3/5+3
Step-by-step explanation:
You need to move y’all variables to one side except Y. Then divide them by 5 to get rid of the 5 attached to the Y. So then you have Y=Mx+b.

Average speed of the entire journey is 3.08 km/hr
Step-by-step explanation:
- Step 1: In the first half, given that the speed = 4 km/h and time = 2 1/2 = 2.5 hrs. Calculate the distance covered.
Distance = Speed × Time = 4 × 2.5 = 10 km
- Step 2: In the second half, given that speed = 2 1/2 = 2.5 km/hr and time = 4 hrs. Calculate the distance covered.
Distance = 2.5 × 4 = 10 km
- Step 3: Calculate average speed.
Average Speed = Total distance/Total time
= 10 + 10/2.5 + 4 = 20/6.5
= 3.08 km/hr
