Answer: 9
Step-by-step explanation:
Add 20, 12, and 32 together then divide by 7 because it says "One week" and a week is 7 days. So, it should be like 20 +12 + 32= 64
64 / (divided by) 7 = 9
Answer:
140°
Step-by-step explanation:
The total of interior angles in a polygon is 720 °
The total of the angles given to you is (100*2+130+125*2) = 580
Then you subtract the total of the angles given from the total value of the interior angles to get 140°
I believe that A and D would be the correct answer. Because both are 30,60,90 triangles and would be congruent. The other 2 triangles only have 1 angle and their side measures are at two different places meaning they cannot be congruent.
Answer:
3 students
Step-by-step explanation:
If everyone in the class has either a pierced nose or ear, we just simply have to add up the total number of hands raised and minus the number of students in the class.
35+8=43
43-40=3
3 students have both a pierced nose and pierced ear.
