Answer 1

Answer:

x = 38°

Step-by-step explanation:

Let's find the internal angles of the triangle, at the base.

We see that one external angle is 134° and we need to find its supplementary angle (a+b = 180°) so:

134° + α = 180°

α = 46°

Now the other base angle:

β + 84° = 180°

β = 96°

We also know that the sum of all angles in a triangle is always 180°:

α + β + x = 180°

x = 180° - α - β = 38°
