Step-by-step explanation:
Answer:
8/5
Step-by-step explanation:
opposite reciprocal
flip sign ±
flip numerator and denominator
Step-by-step explanation:
let m2 be x
then m1 = 4x
Since, m1+m2 = 115
therefore x + 4x = 115
5x = 115
x = 23
so , m2 = 23°
The two angles given are vertical angles which mean they are the same.
x +40 = 60
Subtract 40 from both sides:
x = 20
