Answer:
Step-by-step explanation:
External angle equals to the sum of opposite internal angles
z - 41° + z - 20° = z + 40°
2z - 61° = z + 40°
2z - z - 61° = 40°
z - 61° = 40
z = 40° + 61°
z = 101°

yeah she be correct 2.1
Answer:
(k+10f) (k-5f)
Step-by-step explanation:
k^2+5kf-50f^2
What 2 numbers multiply to -50 and add to +5
10 *-5 = -50
10+-5 = 5
(k+10f) (k-5f)
