Answer:
One triangle can be constructed.
Step-by-step explanation:
Recap that all the interior angles in a triangle add up to 180. With the given measurements of the angles, 70 plus 80 plus 30 equals 180. Each triangle has the sum of 180 degrees. Therefore, there can only be one triangle that can be constructed. I think you were suppose to put can, not can't. Hope this helps!
Answer:
1 yard
Step-by-step explanation:
7/14 is 1/2 while 9/14 is greater than 1/2 but a lot less than a whole. So a strong estimate would assume that it is (1 1/2)-(1/2) for the approximate difference in their throws were
Answer:
(i) Approximately 3 half lifes
(ii) 
Step-by-step explanation:
(i) ∵ The half life of Radon-222 is approximately 3.8 days,
So, the number of half life in 11.46 days =
≈ 3
(ii) Since, the half life formula is,

Where,
= initial quantity,
t = number of periods
= half life of the quantity,
Given,
N = 
t = 11.46 days,
