Answer:
The Answer is 12
x
^4
y
^3
Step-by-step explanation:
Supplementary angles are those that together form strait angle with the measure of 180°.
The first picture doesn't contain supplementary angles, because 41°+124°=165°.
Oh the second diagram you can see three pairs of adjacent suplementary angles:
- ∠KJL and ∠LJN, because m∠KJL=90° (it is right angle) and m∠LJN=56°+34°=90°, then m∠KJL+m∠LJN=90°+90°=180°.
- ∠KJM and ∠MJN, because m∠MJN=34° and m∠KJM=90°+56°=146°, then m∠KJM+m∠MJN=34°+146°=180°.
- ∠NJP and ∠PJK, because m∠NJP=49° and m∠PJK=360°-49°-34°-56°-90°=131°, then m∠NJP+m∠PJK=49°+131°=180°/
Answer: correct choice is 2 and 3 (this is second pair of adjacent suplementary angles)
Answer:
the answer is about 50 minutes
Step-by-step explanation:
5 ÷ 6 = .83 which is about 50 minutes so each lesson is about 50mins

Answer:
2 Six graders: 6/55 chance
2 Seventh graders: 21/55 chance
Step-by-step explanation:
Total: 11 students
6 graders: 4
4/11 for first student and 3/10 for second
4/11 * 3/10 = 12/110 = 6/55
7 graders: 7
7/11 for first student and 6/10 for second
7/11 * 6/10 = 42/110 = 21/55
