Answer:
adjacent angles are 50° and 130°
Step-by-step explanation:
The sum of all 4 angles in a parallelogram is 360°, so the fourth angle must be ...
360° -310° = 50°
Adjacent angles are supplementary, so the other two angles must be ...
180° -50° = 130°
The angles in the parallelogram are either 50° or 130°. Adjacent angles are different.
Answer:
v=18
Step-by-step explanation:
10-3v-1=5(9-v)
first open the bracket
10-3v-1=45-5v
5v-3v=45-9
2v=36
v=18
Answer:
x<5
Step-by-step explanation:
the greater sign will firstly be changed to = for better solving so we obtain
3+9x=4(x+7)by opening bracket
3+9x=4x+28
9x-4x=28-3
5x=25
divide all through by 5x
we obtain
x=5
the greater sign change here
which is x<5
