Answer:
<N=69 and <O=69 Hope This Helps
Step-by-step explanation:
To find conjecture about regular polygon, use the formula

Where, n = number of sides of the regular polygone
1) Triangle
n =3
So, Conjecture of the triangle =

= 120
2) Square
n =4
So, Conjecture of the square =

= 90
3) Pentagone
n = 5
So, Conjecture of the pentagon =

= 72
4) Hexagone
n = 6
So, Conjecture of the pentagon =

= 60.
Answer:
25
Step-by-step explanation:
Since each of the six possible outcomes is equally likely, you can expect to get each of the outcomes 150/6 = 25 times.
if this is wrong, let me know so I can fix it

Area formula for a triangle is 1/2BxH
B=15
H=10
1/2(15)= 7.5
7.5 x 10= 75
So the area is 75 square cm :)
