Answer:
19° 'cause is 52° less than 71°
Step-by-step explanation:
When two angles add to 90°, we say they "Complement" each other, then
a = angle
b = complement
a + b = 90, by definition
a = b - 52
Substitute
(b - 52) + b = 90
b - 52 + b = 90
2b - 52 = 90
2b = 90 + 52
2b = 142
[tex]b = \frac{142}{2} \\b = 71[/tex]
Check
a = 71 - 52
a = 19
