Answer: length when perimeter is 78 units: a=26 ,b=13
Length when perimeter is 156 units:
a=26 , b=52
Step-by-step explanation: Given one side =26 , the other is twice as long
Perimeter of a parallelogram =2(a+b)
Using perimeter=78= 2(26+b)
78=52+2b
78-52=2b
26=2b
b=26/2
b=13
When perimeter is 78 units a=26,b=13
Using perimeter =156 units
156=2(26+b)
156=52+2b
156-52=2b
104=2b
b=104/2
b=52
Answer:
246.979 ft
Step-by-step explanation:
When we draw our picture, we should be able to see that the angle of depression from the point of view is equal to the angle of elevation from the ground. We also know the height, and we are trying to find horizontal <em>x</em>. We must use tan∅ to solve:
tan39° = 200/x
xtan39° = 200
x = 200/tan39°
x = 246.979
Answer:
x=-0.7
Step-by-step explanation:
7x+1.1=-3.8
subtract 1.1 on both sides
7x=-4.9
divide both sides by 7
x=-0.7
False.
