Answer:
Perimeter = (11x + 12)
Step-by-step explanation:
Since, perimeter of a polygon is represented by the sum of measures of all sides,
Perimeter of the given polygon = 3x + (x + 10) + 5x + (2x + 2)
By adding like terms of the expression,
Perimeter of the polygon = (3x + x + 5x + 2x) + (10 + 2)
= (11x + 12)
Therefore, expression for the perimeter is (11x + 12).
Answer:
X= 22
Explanation:
Add 10 to both sides and then x is 22
180 degrees= a whole line
180-102=78
So m13 should equal 78°
Answer:
16
Step-by-step explanation:
use the formula (b/2)^2 to find what number to add to each side of the equation
