Question

Can anyone help???????

Answer 1

The sum of the angles is 180°.

We already know that one angle is 90°, and the other one is 38.

so: 180-(90+38)=52°

the exterior angle+52°= 180° (beacuse the form a flat angle)

so x=180-52

so: x=128°.

Answer 2

128°

Explanation:

We know that,

the exterior angle of a triangle is equal to the sum of the interior opposite angles of a triangle.

Accordingly,

38 + 90 = x

128° = x
