The answer is C. i hope this helps!!!
The sum of interior of all angles in a triangle = 180
Given 3 angles = <span>80°, 2x + 2°, and 5x°
To find x:
</span><span>80°+ 2x + 2 + 5x = 180
7x + 82 = 180
7x = 98
x = 14
answer
x = 14 </span>
The first board is approximately 0.45 the second board is approximately 0.9 and the third board is approximately 19.8
Hello!
695 - 7x = 140
-7x = 140 - 695
-7x = -555
-x = -79.29
x = 79.29
I hope this helps you! Have a lovely day!
