I'm being Timed please hurry. Triangle TUV is rotated as shown on the coordinate grid below, using the origin as the center of rotation. On a coordinate plane, triangle T U V has points (1, negative 2), (7, negative 2), (3, negative 3). Triangle T prime U prime V prime has points (2, negative 0.5), (6.2, 3.8), (4, 0). Which describes the rotation that took place?

A. a 90° clockwise rotation
B. a 90° counterclockwise rotation
C. 45° clockwise rotation
D. 45° counterclockwise rotation

D. 45 degree counterclockwise rotation

Step-by-step explanation: :              

The original image is triangle TUV and it has been rotated counter clockwise to form triangle T'U'V' using the origin as the center of rotation. . The rotation is 45 degrees rotation.                                

Hence, option B is correct.

Plz mark brainliest!

8 2/3 is the answer

step-by-step explanation: just use a calculator

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
