Answer:
22°, 90°,68°
Step-by-step explanation:
you have the solution in the picture
the sum of the interior angles of a triangle (only) is 180°
180 = 4x + 2 + x + 3x +2
180 = 8x + 4
176 = 8x
x = 176 : 8
x = 22 (and you have the value of angle x)
-----------------------
4x + 2 =
4 * 22 + 2 =
88 + 2 =
90°
-------------------------
3x + 2 =
3 * 22 + 2 =
66 + 2 =
68°
------------------------
check
22° + 90° + 68° = 180°
the answer is good
