Answer:
x=21
Step-by-step explanation:
100+3x+x-4=180
100+4x-4=180
96+4x=180
4x=180-96
4x=84
x=21
The answer is 6 degree.
Step by step process
The formula for calculating the measure of each exterior angle of a polygon is (360/n).
The number of sides of 56-gon(n) = 56.
So, each exterior angle
= (360/56)
= 6.43 or
6(approximately)
The numbers on the top depend on how many sides a dice has. Hope this helps.
D because is the equal to the other side but added allá together
Answer:
Step-by-step explanation:
x^2 + 10x + 5 - 30 = 0
x^2 + 10x - 25 = 0
x^2 + 10x = 25
x^2 + 10x + 25 = 25 + 25
(x + 5)^2 = 50 <====
