50°, 130°
Step-by-step explanation:
All measures are in degrees. Let x represent "one angle". Then the other is (180-x) and we can write the relation ...
3x = 20 +(180 -x)
4x = 200 . . . . . . . add x, collect terms
x = 50 . . . . . . . . . . one angle
180 -50 = 130 . . . .the other angle
The measures of each angle are 50° and 130°.

Answer:
And the 95% confidence interval would be given (0.107;0.227).
Step-by-step explanation:
Information given
number of trees with signs of disease
the sample selected
the proportion of trees with signs of disease
The confidence interval for the true proportion would be given by this formula
For the 95% confidence interval the significance is 
and 
, and the critical value would be
And replacing we got:
And the 95% confidence interval would be given (0.107;0.227).
