2x(8+13)

Because 2x8=16 &
2x13=26

26+16=42 which is the same as the 30+12.

It basically looks like this: 2x8+2x13.
There's also the rule that you have to solve the multiplication before the addition one.

(2x8)+(2x13) also works

I really need help with this

Answer:

x = 67

Step-by-step explanation:

If the measure of the entire chord is 166°, then if you add the two angles that form it together, it will equal 166.

So,

x + 15 + x + 17 = 166

Simplify.

2x + 32 = 166

Subtract 32 from both sides.

2x = 134

Divide both sides by 2.

x = 67

I hope this helps! Feel free to ask any questions!
