Answer:
2= 95 degrees
3= 25 degrees
1= 60 degrees
5= 25 degrees
4= 95 degrees
Step-by-step explanation:
2) Straight line is 180 degrees so
180-85=95 degrees
3) I got 25 degrees because it's a corresponding angle of X, which is parallel to 25.
1) A triangle is always 180 degrees, 95+25=120 180-120=60
5) Its another corresponding angle to 25
4) Straight line is 180 degrees 60+25=85 180-85=95
Or you could of worked out the bottom 85 and minus it from 180 which will also correspond to 4
Ana has 4 coins with different values(5, 10, 20, 50) and you are asked to find how many different sums they can make. You can see every value as a separate combination and multiply it.
There is 1 coin for every value and it can be either used or not used, so there are two probabilities for each coin value. The calculation would be:
C(2,1)= 2!/1!= 2
There are 4 values of coins, so the total probability would be:
4 * C(2,1)= 4*2=8 ways
