In order to get an 81 average,
the student has to get 81x5=405
71+96+90+73+?=405
330+?=405
405-330=75
he needs to get an 75
3n+(4n-15)=90
3n+4n-15=90
7n=105
n=105/7
n=15
---------------------
Angle LQK is 4n-15
If n=15
Angle LQK = 4(15) - 15
= 60 - 15
= 45
Answer:

Step-by-step explanation:
Answer:
w = 8
Step-by-step explanation:
Based on the altitude theorem of a right triangle, we have:
w + 4 = √(24*6)
w + 4 = √144
w + 4 = 12
w + 4 - 4 = 12 - 4
w = 8
