Answer:
13 years old
Step-by-step explanation:
2x - 4
11-5=6
6 x 2 = 12
12 - 4 = 8
8 + 5 = 13
CHECKING JUST TO MAKE SURE:
13 - 5 = 8
11 - 5 = 6
6 x 2 = 12
12 - 8 = 4
You can now tell that it is correct.
- We know, sum of all angles of a triangle is 180°.
- Therefore, by the problem
72 + 64 + (4x+20) = 180
or, 156 + 4x = 180
or, 4x = 180 - 156
or, 4x = 24
or, x = 24 ÷ 4 = 6
