Hey if this helps you can I pretty please have brainliest if possible!
Supplementary angles are angles that add to 180 degrees......in this case "x" would equal 22
Exterior angle sum of an polygon (shape) is 360 degrees (this is a property)
x + 98 + 41 + 76 + 86 = 360
Therefore x = 59
Please double check the equation I have written. Your picture is a bit blurry therefore I can really tell what number is 6 and 8. Sorry
First, you combine like terms. I would start by circling the term and the sign in front of it. (A term is a piece separated by an addition/subtraction sign.) You can only combine terms with the same variable. 4.8a-2.1a-6.3b+7b is the same as your equation, just rearranged. Then, subtract (4.8a-2.1a) which is 2.7a. Add (-6.3b to 7b) The answer is 0.7b. If you have any questions, you can message me!
