Find x show ur work !!

Elis [28]

Answer:

x = 10

Step-by-step explanation:

A triangle's angles add up to 180 degrees, so 180-90 (the right angle) is 90 degrees. That means that

4x+6+3x+14 = 90. Then we simplify so

7x + 20 = 90. Then we can subtract 20 from each side so

7x = 70. Then, we find that

x = 10.
