Need with the worksheet i will give brainliest and lot of points who answers.

45, 75 and 25 degrees

Step-by-step explanation:

First problem:  (2x) degrees = 90 degrees; thus, x = 45 degrees.

Second problem:  same principle:  x + 15 degrees = 90 degrees (that is, x and 15 degrees are complementary angles).  Thus, x = 75 degrees.

Third problem:  4x - 10 degrees = 90 degrees.  Adding 10 to both sides, we get 4x = 100, and so x = 25 degrees.
