Answer:
1. a + 27° = 90°
a = 63°
2. 3b = 90°
b = 30°
3. 2c + 40° = 90°
2c = 50°
c = 25°
4. f + 82° + 41° = 180°
f = 57°
d = 57°
e = 82°
5. g + 74° + 53° = 180°
g = 53°
6. i + 64° = 90°
i = 26°
h + 90° = 180°
h = 90°
1. m∠5 = m∠6
6x = 4x + 6
2x = 6
x = 3
m∠5 = 6x = 6(3) = 18°
m∠6 = 4x + 6 = 4(3) + 6 = 18°
