Answer:

x = 100

Step-by-step explanation:

The sum of the angles of a triangle are 180 degrees

x+ 42+ 38 = 180

Combine like terms

x + 80 = 180

Subtract 80 from each side

x+80-80 = 180-80

x = 100

Answer:

Easy!

Step-by-step explanation:

First, we have to know that:

The Sum of All Angles in a Triangle is 180 Degrees

(Self-explanatory, really)

This means that 42, 38, and x added together will equal 180 degrees, thus me set up our equation:

[tex]42+38+x=180\\x=100[/tex]

See? Simple.

Hope this helps!

FYI Remember that x= 100 Degrees
