Let's solve this problem step-by-step.
STEP-BY-STEP EXPLANATION:
Let's first eatablish the following formula:
Sum of all angles at a point = 360°
Therefore:
( 4x + 3 ) + ( 2x + 16 ) + ( 35 ) = 360
6x + 54 = 360
6x = 360 - 54
6x = 306
x = 306 / 6
x = 51
FINAL ANSWER:
Therefore, the answer is:
x = 51°
Hope this helps! :)
Have a lovely day! <3
