I think the it would be some like y-8
Answer:
511.425
Step-by-step explanation:
Easy add them all together = 2045.7 then divide by how many numbers are there so 4 thats 511.425 and theres ur answer please mark me as brainlest!
ABCD is a parallelogram ⇒ BE = DE
So: 7x - 12 = 3x + 4
⇔ 7x - 3x = 4 + 12
⇔ 4x = 16
⇔ x = 16/4 = 4
⇒ BE = 7(4) - 12 = 28 - 12 = 16
⇒ DE = 3(4) + 4 = 12 + 4 = 16
⇒ BD = BE + DE = 16 + 16 = 32
Answer: BD = 32
Ok done. Thank to me :>
Answer:
The angle is 50 degrees.
Step-by-step explanation:
You'll see, the angle that is on the left of the 70° angle has to be 110°, because a straight line has 180°.
Now, the inner angles of a triangle have to sum 180°. So if the lower angle is 110° (because you just calculated it), and the upper angle is 20°, the third angle is:
180° = 110° + 20° + x
180° = 130° + x
180° - 130° = x
50° = x
Now this third angle is on the bottom left part of the triagle, and it's 50°. It also opposite to the angle 1, which is the one you want to calculate. Because they are opposites, they are identical, meaning that they both are 50°. This is due to a geometrical rule.
