The sides of a parallelogram are 40 and 70 feet long,and the smaller angle has a measure of 36.Find the length of the longer dia
gonal to the nearest whole number
1 answer:
Answer:
105 feet.
Step-by-step explanation:
The longer diagonal is opposite the longer angle in the parallelogram.
The longer angle = 180 - 36 = 144 degrees. (Reason: he same side angles are supplementary).
So, by the law of cosines:
x^ 2 = 40^2 + 70^2 - 2*40*70 cos 140 where x = the diagonal.
x^2 = 11030.50
x = 105.03 feet.

First, you put each fraction into its greatest common denominator:
5/20 - 12/20. This then gives you the answer - 7/20.
If t=-3 (hopefully it does) then it's 6+-12/10. This is -6/10=-3/5
Answer:$3207
Step-by-step explanation
A=p(1+r/100)^n
A=1000×(1+6/100)^20
A=1000×(1.06)^20
A=1000×3.207
A=$3207
A number greater than 40 and have 5 in the tenth place is 50
