What’s the measure of A?

x = 11

Step-by-step explanation:

Complementary angles = 90*

Set the two equations equal to 90. Solve

4x + 6 + 4x - 4 = 90

8x +2 = 90

8x = 88

x = 11

Plug it in to see if it makes equation true

4 (11) + 6 + 4 (11) - 4 = 90

44 + 6 + 44 - 4 = 90

50 + 40 = 90

90 = 90

i can't solve unless i know what the line is
