Answer:120
Step-by-step explanation:
☆ given that ,
ABCD is a parallelogram
☆ we know that ,
opposite angles of a parallelogram are equal.
Therefore ,
therefore , ∠B = 3x = 3 ( 26° ) = 78°
thus option ( A ) is correct ~

Answer:
Step-by-step explanation:
m∠2 = 52° [Alternate interior angles]
m∠1 + m∠2 = 180° [Linear pair of angles are supplementary]
m∠1 = 180° - 52°
m∠1 = 128°
m∠3 = 47° [Alternate interior angles]
m∠5 + 52° + 47° = 180° [Sum of linear angles is 180°]
m∠5 = 180° - 99°
= 81°
m∠4 + 47° = 180° [Sum of consecutive interior angles is 180°]
m∠4 = 180° - 47°
m∠4 = 137°
Answer: f(n) = {f(1)=-4
{f(n) = f(n-1) / 20 if n > 1
Or Answer B.

Answer:
1 makes this problem true
Step-by-step explanation:
-1t+14=3t+10
-1(1)+14 = 3(1)+10
-1 +14 =3+10 , 13=13
So 1 makes this problem true
