Answer:
The interior angles are 70°,65°,80°,155° and 170°
Step-by-step explanation:
step 1
Find the sum of the interior angles of the pentagon
The sum is equal to
S=(n-2)*180°
where
n is the number of sides of polygon
n=5 (pentagon)
substitute
S=(5-2)*180°=540°
step 2
Find the value of x
Sum the given angles and equate to 540
x+(x-5)+(x+10)+(2x+15)+(2x+30)=540°
7x+50=540°
7x=490°
x=70°
step 3
Find all the angles
x=70°
(x-5)=(70-5)=65°
(x+10)=(70+10)=80°
(2x+15)=(2*70+15)=155°
(2x+30)=(2*70+30)=170°
Ax + By = C
y+1 = -6 (x+3)
y= -6x - 17
not sure if y = -6x - 17 is the answer or 6x + y = -17
they are equivalent its just moving over the x to match Ax + By = C
Answer:
0.1
Step-by-step explanation:
Just google the answer and it will give it to you and if it is not 0.1 then try 0.11 because there is a LOT of 1's.
Answer:
Open circle
Step-by-step explanation:
A closed, or shaded, circle is used to represent the inequalities greater than or equal to ( ) or less than or equal to ( ). The point is part of the solution. An open circle is used for greater than (>) or less than (<). The point is not part of the solution.
