Answer 1

To find angle \( x \) in the triangle with a right angle at the top vertex, we can use the fact that the sum of the angles in a triangle is always 180 degrees.

We know:
1. The right angle at the top vertex is 90 degrees.
2. The exterior angle at the right vertex is 152 degrees.

An exterior angle is equal to the sum of the two remote interior angles of the triangle. Therefore, we can express this relationship as follows:

\[
\text{Exterior angle} = \text{Angle at left vertex (x)} + \text{Right angle (90 degrees)}
\]

Plugging in the values we have:

\[
152 = x + 90
\]

To isolate \( x \), subtract 90 degrees from both sides:

\[
152 - 90 = x
\]
\[
62 = x
\]

Therefore, angle \( x \) is \( 62 \) degrees.

The correct response is:
**62°**
