Answer:

x = 25

Step-by-step explanation:

The sum of the angles of a triangle is 180 degrees.

90 + x+ 2x+15 =180

Combine like terms

105+3x = 180

Subtract 105 from each side

105+3x-105 = 180-105

3x =75

Divide each side by 3

3x/3 = 75/3

x = 25

Answer:

25°

Step-by-step explanation:

2x + 15° + x + 90 °= 180° ( being sum of angles of triangle)

3x + 105° = 180 °

3x = 180 °- 105°

3x = 75°

x = 25°

hope it helps :)
