Answer:
The sum of the interior angles of any polygon is (n-2)*180° (n being the number of sides) so for a triangle the sum of the interior angles is 180°. The sum of the interior and exterior angles is also 180°. To work out which sets are possible you subtract each number from 180° and then add all three answers together. If you get 180° then that set of numbers is possible. Using this method, you will find that the following sets can be the measures of the exterior angles of a triangle:
its
120°, 120°, 120°
Answer:
(x+10)(x+10)
or (x+10)²
Step-by-step explanation:
this factories can use this
a² + 2ab + b²
; (a)² + 2(a)(10) + (b)²
= (a+b)²
hope it helps you ☺️

Answer:
1.86 < t < 2.31
Step-by-step explanation:
given that a onesided test of a hypothesis, based on a sample of size 9, yields a Pvalue of .035.
Since one tailed test we have one side shaded rejection region
Sample size = 9
Degree of freedom = 9-1 =8
For df 8, for one tailed we find test statistic is 2.090
The interval containing this is only
1.86<t<2.31
Hence the best choice for possible range of t values that yields this p value is
1.86 < t < 2.31
