Answer:

X = 40°

Step-by-step explanation:

The sum of the interior angles in a triangle is 180°. This means that:

2X + 35 + 2X - 15 = 180° - we can simplify this

4X + 20 = 180° - now, subtract 20 from both sides

4X = 160° - finally, divide both sides by 4

X = 160 ÷ 4 = 40°

X = 40°

Hope this helps!
