Sagot :

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

Hope this helped :)
x=14
angle cab= 28 because 2*14 = 28
angle cba = 22 because 3*14=42-20=22
