This is the concept of geometry, we are required to calculate for the length of the shortest side. The shortest side is the side opposite to the smallest angle; Therefore using sine rule we shall have:
a/sin A=b/sinB=c/sinC
let a=20 and A=100
b=x and B=20
thus the shortest side will be given by:
20/sin 100=x/sin 20
x=(20sin 20)/100
x=6.95 feet
The answer is 6.95 feet
Answer:
1/15
Step-by-step explanation:
P(a blue highlighter than a pink)
P(blue)=3/10
P(pink)= 2/9
3/10•2/9=
1/15
Uhhh… none of these seem right… it is 73….
Answer:
5.5
Step-by-step explanation:
2x -3 = 8
then
2x = 8 + 3 = 11
means
2x = 11
then
x = 11 ÷ 2
x = 5.5
___________________
we change the sign (- or +)
then take the number to the other side of the equal (with the changed sign)
leaving the x alone so that we can answer the equation..
_____________
to make sure
2×5.5 -3 = .....
it will be 8
Answer:
100 + 100 + 25 + 25 + 13 + 13 + 9
Step-by-step explanation:
There are 334 ways to do it. The answer shown above is shortest sum. Perhaps the longest is 6×9 + 33×7, for a total of 6 + 33 = 39 numbers.
_____
Given the above sum, certain replacements can be made:
13 + 13 + 9 = 7 + 7 + 7 + 7 + 7
25 = 9 + 9 + 7
25 + 25 = 13 + 9 + 7 + 7 + 7 + 7
25 + 25 + 25 = 13 + 13 + 13 + 9 + 9 + 9 + 9
100 = 25 + 25 + 25 + 25
These can be iterated to whatever depth or combination may tickle your fancy.
