What is the value of x?

Enter your answer in the box.

Answer 1

The sum of the inner angles of a triangle is always 180 degrees.

In your triangle, this translates to

$39+102+x = 180$

$141+x=180$

Subtract 141 from both sides to get the answer

$x = 180-141=39$

Answer 2

Answer:

39° is your answer

Step-by-step explanation:

The sum of the interior angles for a triangle is 180°

Set all the interior angles equal to 180

39 + 102 + x = 180

Simplify.

x + 141 = 180

Isolate the x. Subtract 141 from both sides

x + 141 (-141) = 180 (-141)

x = 180 - 141

x = 39

39° is your answer
