Answer:
x = 25
Step-by-step explanation:
We know that the remaining angles add up to 90°, because the right angle (triangles have 180° total.)
2x + 15 + x = 90 | Given
3x + 15 = 90 | Combine x
3x = 75 | Subtract 15
x = 25
Sin is x
tan is y

First distribute the invisible 1 to the numbers in the parenthesis.
3x + 2 - 4x
Combine like terms.
-x + 2
