Answer: x=5, angle 1 = 140 degrees, angle 2 = 40 degrees, angle 3 = 65 degrees
Step-by-step explanation:
1)
19x-18=(7x+1)+(10x-9)
19x-18=17x-8
2x=10
x=5
2)
angle 1 = 60+80
angle 2= 180-(60+80) or 180-angle 1
angle 3 = 180 - (180-105) - angle 2 = 105 - angle 2
Answer:
Step-by-step explanation:
x=0.6121212... (1)
10x=6.121212... (2)
1000 x=612.121212... (3)
(3)-(2) gives
990 x=606
330x=202
165x=101
x=(101)/165
An equivalent statement is CD overbar congruent to EF overbar.
What is a line segment?
The line segment has two fixed-length endpoints, A and B. The distance between this line segment's endpoints A and B is its length.
Here,
Line segment CD is congruent to line segment EF and in geometry, an overbar represents a line segment.
So, we can say that the CD overbar means line segment CD and the EF overbar means line segment EF.
Hence, An equivalent statement is CD overbar congruent to EF overbar.

Answer:
x=8/9
Step-by-step explanation:
-3.1x+7-7.4x=1.5x+6(x-3/2)
-3.1x-7.4x+7=1.5x+6x-9
-10.5x-1.5x-6x=-9-7
-18x=-16
18x=16
x=16/18
simplify
x=8/9
