Answer:
41°
Step-by-step explanation:
Supplementary angles are angles that has their sum total of angles as 180°.
If two angles ∠x and ∠ y are supplementary, this means
∠x+∠y = 180° ... (1)
Since ∠y = 139°, to get ∠x, we will substitute the value of ∠y in equation 1 to have;
∠x + 139° = 180°
∠x = 180°-139°
∠x = 41°
Therefore the measure of ∠x is 41°

Answer:
Distance: 8.5440037453175
Step-by-step explanation:
Distance: 8.5440037453175
Steps:
Distance (d) = √(-7 - -10)2 + (-1 - -9)2
= √(3)2 + (8)2
= √73
= 8.5440037453175
Slope and Angle:
ΔX = -7 – -10 = 3
ΔY = -1 – -9 = 8
Slope (m) =

Equation of the line:
y = 2.6666666666667x + 17.666666666667
or
y =

When x=0, y = 17.666666666667
When y=0, x = -6.625
Answer:
60degrees
Step-by-step explanation
To get the angle x, you must first know that the sum of angle at a point is 360degrees. Hence;
x + <ADB + <CDB = 360
x +150 + 150 = 360
x+ 300 = 360
x = 360 - 300
x = 60
Hence the value of x is 60degrees
