10(4x-1) is the answer to your question my friend
Answer:
it's answer is 73°
Step-by-step explanation:
< DCB = 50°
< ACB = x
< CAB = 57°
< ABC = < DCB = 50° {Being alternate angles }
Now
x + 50° + 57° = 180° { being sum of angles of triangle }
x + 107° = 180°
x = 180° - 107°
Therefore x = 73°
Hope it will help :)❤
11
with the values plugged in the equation is 3(-3)+4(5)=k which simplifies to -9+20=k and then to 11=k
1a+18=7a
18=7a-1a
18=6a
6a=18
a=18/6
a=3
Answer:
C
Step-by-step explanation:
C is the answer because a1=7 , d=-4 and so it's
an=an+(n-1)d
