Answer:
45
Step-by-step explanation:
The sum of angle in a straight line is 180
=> 3n + (4n - 15) + 90 = 180
3n + 4n + 75 = 180
7n = 180 - 75 = 105
n = 15
Angle ZLQK = 4n - 15 = 4*15 - 15 = 60 - 15 = 45

Answer:
The numbers are 17 and 5
Step-by-step explanation:
x + y = 22
x - y = 12
Add y to both sides of the equation
x = 12 + y
Substitute new value for x into first equation
12 + y + y = 22
Add the y's
12 + 2y = 22
Subtract 12 from both sides
2y = 10
y = 5
22 - 5 = 17
The numbers are 17 and 5
Hope this helps :)
