Answer:
x=7/2
Step-by-step explanation:
11=4x−3
Step 1: Flip the equation.
4x−3=11
Step 2: Add 3 to both sides.
4x−3+3=11+3
4x=14
Step 3: Divide both sides by 4.
4x
/4
=
14
/4
x=
7/
2
Step-by-step explanation:
Continuation of the answer
4x=180 degrees
X=180/4=45 degrees.
Answer:
8
Step-by-step explanation:
Considering the given value of sum of interior angles with exclusion of one to be 1070 then we can write it as
1070=180(n-2) where n is the number of sides required here.
Making n the subject of the formula then following step by step


Therefore, the shape is octagon and it has 8 sides.
