Answer:
m∠P = 29
Step-by-step explanation:
Straight line is 180 so:
56 + x = 180
x = 124
So m∠Q is 124 and a triangle is 180 so now:
124 + 27 + h = 180
151 + h = 180
h = 29
m∠P = 29
The given relation is
n·(3n-7) = 20
In standard form, this is
3n² -7n -20 = 0
(n -4)(3n +5) = 0
n = 4 or -5/3
The number is -5/3.
