What is x=? I got part a but what does x=?

I think x = 44°

Step-by-step explanation:

Finding the exterior angle:

180° - 45° = 135°

We know that x is multiplied by 3 (3x) so we divide 135 by 3.

135° / 3 = 45°

We know that we have to add 3° to the product of 3x, so we know the product of 3x will be less than 135°. The product should be 135° after 3° is added to it.

Trying a few possible answers:

43° × 3 = 129°

129° + 3° = 132°

That one wasn't quite right.

44° × 3 = 132°

132° + 3° = 135°

:D

option 1

data plot with   3 dots over 33, 1 dot over 34, 2 dots over 35, no dot over 36, 1 dot over 37, 2 dots over 38, 4 dots over 39, and 2 dot over 40.

do you have the measurements?
