Answer:
y=2x-3
Step-by-step explanation:
The value of X is 39 degrees. You have to add 102 degrees and 39 degrees to get 141 degrees. All triangles equal up to 180, so subtract 141 from 180, and you get 39 degrees.
Answer:
A
Step-by-step explanation:
it is Arithmetic because if you subtract 12 from 40 you'll get 28 , same for the others. but if you get the common ratio by dividing 40/12 which is 3.333... it's doent work for the sequence
Answer:
120°
Step-by-step explanation:
The angle just below 'x' is 40° (alternate angles/parallel lines)
40 + x + 20 = 180 ( straight line)
x = 120°
