Answer:
70 degrees
Step-by-step explanation:
Angle BZA = Angle BZC = 20 degrees
Reason : These two angles are Vertically opposite angles.
Angle BZA + Angle BZC = 90
20 + Angle BZC = 90
Angle BZC = 90 - 20
Angle BZC = 70 degrees
3x and 2x are alike terms, as they have the same variable
Answer:m+3
Step-by-step explanation:
No beacuse 1/4 would be less that 1/2 it's common sense
Cos α = sin (90-α) so cos 19 = sin 90-19 = sin 71
