Answer:
Explanation:
FIrst we find the angle that is complementary to 55 degrees.
55 + k = 90
k = 90 - 55 = 35
Now we find the blue angle
The blue angle forms the interior angle of the triangle; therefore,
35 + 35 + blue = 180 (the angles in a triangle add up to 180 )
70 + blue = 180
blue = 180 - 70
blue = 110
Finally, we are in a position to find the yellow angle x.
The yellow angle x is supplementar to the blue angle; therefore,
110 + x = 180
subtracting 110 from both sides gives
x = 180 - 110
x = 70
which is our answer!
