Answer:
p=2 and p=4/3
Step-by-step explanation:
3p² - 10p + 8 =0, a = 3, b = - 10, c = 8
We can use quadratic formula
p = ( - b +/- √(b² - 4ac))/2a
p = ( 10 +/- √(10² - 4*3*8))/2*3
p1 = ( 10 + √(100 - 96))/2*3 = (10 + 2)/6 = 2
p2 = ( 10 - √(100 - 96))/2*3 = (10 - 2)/ 6 = 8/6 = 4/3
$40
cost of 1 trophy= $5/6
cost of 48 trophies=48×5/6 =$40
x° = 79°
z° = 101°

You got to add 120.75 to 45.82 then you subtract it from 185.90
comment if this helps :)
190.5
--------------------------
For a polygon of N sides, the sum is
N*(180-360/N) = N*180 - 360 degrees
Subtract (120 +93 +108 +101) from 540 for your answer
