Answer:
x = 14°
Step-by-step explanation:
There are two ways you can go at this.
1) an exterior angle is equal to the sum of the remote interior angles
124° = (2x) +(180° -6x)
-56° = -4x
x = 14°
__
2) sum of exterior angles is 360°
124° +6x +(180° -2x) = 360°
4x = 56°
x = 14°
Answer:
Y= 5
Step-by-step explanation:
Let's guess and check.
Let's try 8
2 × 8 = 16
3 × 8 = 24
4 × 8 = 32
16 + 24 + 32 = 72 ==> too high
Let's try 6,
2 × 6 = 12
3 × 6 = 18
4 × 6 = 24
12 + 18 + 24 = 54 ==> perfect
Wow, I did not think I'd get that on the 2nd try.
So the numbers are 12, 18, and 24.
