Answer:
50; 72; 8; 57.9
Step-by-step explanation:
1. sqrt((30/2)^2 + (20)^2) = sqrt(15^2 + 20^2) = sqrt(225 + 400) = sqrt(625) = 25 (radius) * 2 = 50 (diameter)
2. 360 (degrees in a circle)/5 (sides in a pentagon) = 72 degrees
3. 360 (degrees in a circle)/x (sides) = 45 --> 360/45 = x --> 8 sides = x
4. sqrt(7^2 + (12/2)^2) = radius --> sqrt(49 + 36) --> sqrt85 * 2pi = circumference --> 57.9281062 = circumference --> 57.9
Answer:
-7 is the answer!! :) hope this helps
Answer:
twenty four
Step-by-step explanation:
Answer:
second option: 32.8 m, 48.2 m, 81.1 m
Step-by-step explanation:
20.2 m + 20.4 m = 40.6 m. which is bigger than 20.6 m. so yes
32.8 m + 48.2 m = 81 m. which is smaller than 81.1 m. so no
12.8 m + 25.7 m = 38.5 m. which is bigger than 35.9 m. so yes
35.6 m + 49.9 m = 85.5 m. which is bigger than 83.2 m. so yes
Answer:
It is right
Step-by-step explanation:
square all sides
we have 16, 32, 48
add the two shortest sides, which equal the third side
the triangle works with the pythagorean theorem, so of course it is right :)
