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
1. vertical angle theorem and triangle angle sum theorem
2. The sum of the interior angles of a triangle = 180
so < x = 180 - (70 + 30) = 180 - 100 = 80
and < y is a vertical angle to < x...and vertical angles are equal..
so < y = 80
36 ways to roll 2 dice
There are 10 ways to roll 1 thru 5…
Thus there are 26 / 36 ways to roll >5 (13/18)
