Every triangle has an angle measure of 180 degrees.
so 42+20+x (where x is the measure of the third angle)=180
Combine like terms.
62+x=180
Subtract 62 from both sides
x=118.
Answer:
N: n = 5 sides
side length: a = 23.2 m
inradius: r = 15.966 m
circumradius: R = 19.7351 m
Area: A = 926.03 m2
perimeter: P = 116 m
interior angle: x = 108 °
exterior angle: y = 72 °
Description:
We use the calculations on the shape 16 and 23.2. Side length is 23.2. Pi is 16. calculate the numbers and all the answers are added above.

Solve for x
Divide both sides by -4
X= - 10/4
Now simplify by dividing top and bottom by 2
X= -5/2 or - 2 1/2
Answer:
4x+12
Step-by-step explanation:
4(x+3)=4x+12.
You use the distributive property by multiplying both numbers in the parentheses by 4
