First you will subtract right to left and then what ur left with is the sum.
Answer:
Step-by-step explanation:
pentagon , penta (five in Greek) has 5 sides and 5 interior angles
Answer:
thats all i know
Step-by-step explanation:
1.5+8
2.3×4
C
Y=X+9
9 is called y intercept that's where pt starts
The number is front of X is called slope if no number it's 1 so it's 1/1 one up and one right up positive right positive start from 9
You apply the sum of interior angles formula ie. (n-2)180. n=number of sides
since a pentagon has 5 sides it will be (5-2)180=540.
now add everything. x-5+x-6+2x-7+x+2x-2=540.
Solve for x: 7x-20=540
7x=540+20
7x=560
x=560/7
x=80
