Hello,
If we look at the solution we can calculate this very easily
A is 40
B is 121
C=y
D=x
THe answer
x=46
y=13
z= 116
Step-by-step explanation:
9514 1404 393
Answer:
Step-by-step explanation:
The marked external angle at B is "corresponding" to the internal angle BAD, so is the same measure. This means ...
z° +40° = 121°
z° = 81°
__
Adjacent angles of a parallelogram are supplementary, so ...
∠CDA +∠BAD = 180°
x° + 121° = 180°
x° = 180° -121°
x° = 59°
__
Alternate interior angles are congruent, so ...
y° = 40°

2x + 3*6 = 36
2x = 36-18
2x = 18
x = 9
There isn't enough info to determine that, I believe. You would need an equation that would allow me to determine the minimum output for an A.
solve for "x".
what about "y"? well, y = 240 - x
Answer:
<u>x = 50°</u>
Step-by-step explanation:
2x = 140 - 40
2x = 100
x = 100/2
<u>x = 50°</u>
We need the length, the width and the height
