Sum of inside angles of a polygon= 180º(n-2)
n=number of sides.
This polygon has 6 sides, the sum of all its angles would be=180º(6-2)=720
let´s:
xº=inside angle
xº=720º-sum of the others inside angles.
xº=720º-(75º+130º+120º+105º+145º)=720º-575º=145º
yº=180º-xº=180º-145º=35º
Answer: yº=35º
Answer:
Option C
Step-by-step explanation:
Addition theory of probability is used to determine the probability for union of two or more sets.
P(AUB) = P(A)+P(B)-P(AB) is the addition theory of probability for two sets A and B.
P(AUBUC) = P(A)+P(B)+P(C)-P(AB)-P(BC)-P(CA)
for 3 sets
This can be extended to any number of sets
So addition theory has nothing to do with independent events both occurring
Option c is the right answer.
Answer:
7
Step-by-step explanation:
use distributive property first
2x-4=10
then, add positive 4 to -4 and 10 because opposite signs cancel out
2x=14 then we divide
Caitlin = 20 laps
Hannah = 4/5 as many laps
Multiply the laps swan by Caitlin (20) by 4/5
20 x 4/5 = 80/5 = 16
Hannah swam 16 laps
