Question

Find the value of X.

Answer 1

For this case we have an isosceles triangle, since they indicate that two of its sides are equal.

So, we have that the unmarked angle is also given by x degrees.

We know, by definition, that the sum of the internal angles of a triangle is 180.

So:

$2x + 38 = 180$

Clearing the value of "x" we have:

$2x = 180-38\\2x = 142\\x = \frac {142} {2}\\x = 71$

So, the angle x is 71 degrees

Answer:

$x = 71 \ degrees$

Answer 2

Answer:

x=71

Step-by-step explanation:

180-38=2x

142=2x

x=71
