Answer:
10
Step-by-step explanation:
1 2 3 4 5
1 shakes hands with 2,3,4,5
2 shakes hands with 3,4,5 but not with 1 because they already shook hands once
similarly, 3 only shakes hands with 4 and 5, same reason as abov
4 with 5 only, same reason
Answer:
12
Step-by-step explanation:
c = sqrt(a^2+b^2)
Imput numbers and solve for b!
Answer:
a=21
AB=23.9
BC=19.5
CD=(23.9)
AD=19.5
Step-by-step explanation:
Each pair of parallel sides are equal in a parallelogram. Sense both pairs use the same variable we can just choose the easiest to solve which would be:
a-1.5=19.5
add 1.5 to both sides
a=21
now substitute 21 in for a in each equation.
AB=CD so
AB=23.9
BC=AD so
BC=19.5
CD=(21)+2.9 so
CD=(23.9)
AD is given so
AD=19.5
Answer:
270° counterclockwise
Step-by-step explanation:
10/6 = 1 2/3
This is because 5 + 5 =10/6
Divide 19 by six.
This gives you 1 2/3
