Sum of angles in a triangle is 180°
90 + (x + 15) + (2x) = 180
90 + x + 15 + 2x = 180
105 + 3x = 180
3x = 180 - 105
3x = 75
x = 75 ÷ 3
x = 25
Smaller angle = x + 15 = 25 + 15 = 40°
Larger angle = 2x = 2(25) = 50°
Answer: 50°

Answer:
x = 27/2
decimal form - 13.5
Solve for
x by simplifying both sides of the equation, then isolating the variable.
Answer:
AC = 8
Step-by-step explanation:
AC = 4x + 8
BE = x + 2
x + 2 = x + 2
2x = 2 - 2
2x = 0
2x\2 = 0/2
x = 0
AC = 4x + 8
AC = 4(0) + 8
AC = 0 + 8
AC = 8
