Ответ:
95x + 65 = c
Step-by-step explanation:
Ответ:
Since they are complementary, angles A and B must add to 90°. Make an equation:
A + B = 90
And solve it for B, substituting B+6 in for angle A:
A + B = 90
B + 6 + B = 90
2B + 6 = 90
2B = 84
B = 42°
Now you know B = 42°. Find A using A = B + 6. Since A is 6° greater than B, that makes A = 42° + 6° = 48°.
A = 48°
B = 42°
