Answer:
X =14
Step-by-step explanation:
All numbers in degrees
1. because All triangles have internal angles that add up to 180
1) 180 - 90 = 90
1. you subtract 90 because all right angles = 90 and you have one right angle
2) 90 = 2x + 3x-20
2. subtract the other angles from the whole (90)
3) 90 = 5x - 20
3. combine like terms
4) 70 = 5x
4. Subtract 20 from whole
5. divide by 5 on both sides
5) X = 14
