One side is 9.
second side (3x+1) is 28.
third side (4x-9) is 27.
Step-by-step explanation:
Total no. of horses and chicken=24
C+H=24
Total no. horses be =24-C
Total no. legs=66
---66=4(24-C)+2C { As horses have 4 legs and chicken has 2 legs}
66=96-4c+2c
66-96=-2c
-30=-2C
Chicken=15
Therefore no. horses=24-C
=24-15
=9horses
There fore no. of chicken legs=15×2 = 30 legs
Therefore no. of horse legs=9×4=36 legs
Since A and B are the midpoints of ML and NP, we can say that AB is parallel to MN and LP. In order to find ∠PQN, we can work with the triangles PQB and NQB. According to SAS (Side-Angle-Side) principle, these triangles are congruent. BQ is a common side for these triangles and NB=BP and the angle between those sides is 90°, i.e, ∠NBQ=∠PBQ=90°. After finding that these triangles are equal, we can say that ∠BNQ is 45°. From here, we easily find <span>∠PQN. It is 180 - (</span>∠QNP + ∠NPQ) = 180 - 90 = 90°
