Answer:
47°, 86°
Step-by-step explanation:
The other base angle is congruent, so measures 47°.
The third angle brings the total angle measure to 180°, so has measure ...
180° -2(47°) = 86°
The other two angles have measures 47° and 86°.
Theorem:
Vertical angles are congruent.
If the angles are vertical angles, they are congruent.
Congruent angles have the same measure.
If <2 measures 31 deg, then <1 also measures 31 deg.
So basically an arithmetic sequence has a common difference, a number which is either added or subtracted at a constant rate (only that number). A geometric sequence is the ratio between two numbers, meaning they are either multiplied or divided by the same number. The sequence would be neither if it follows none of these patterns. So by this logic:
14. Arithmetic, 15. Geometric, 16. Neither, 17. Geometric
Answer:
The new class average for number of siblings is 3 5/26 or 3.1923
Step-by-step explanation:
if the average is 3 siblings per student and there are 25 students, it means that we can calculate the number of siblings
25 * 3 = 75
we add the 8 new siblings and we also add the student
75 + 8 = 83
25 + 1 = 26
To find the new average of siblings per student, we divide the number of siblings by the number of students.
83 / 26 = 3 5/26
the new class average for number of siblings is 3 5/26 or 3.1923
