What is the measure to the nearest degree of the smallest angle in a triangle whose vertices are r(3, 3), s(-2, 3), and t(-2, -3)? 47º 40º 49º 51º i got 50 but that isn't an option. 49?

check the picture below.

make sure your calculator is in Degree mode.

Step-by-step explanation:

First, we need to graph the triangle.

The image attached shows that's a right triangle, where its right angle is placed at vertex S.

First, we need to find the length of sides RS and TS, then we apply trigonometric reasons to find both acute angles.

Now, we use the tangent reason to find both acute angles

Therefore, the smallest angle rounded to the nearest degree is 40°.

$12. that is my answer.
