Answer:
15.9
Step-by-step explanation:
I don't know if this is right I'm sorry if it isn't.
15×0.06=0.9
15+0.9= 15.9
Again I am sorry if it is not right, please let me know if it was right
Solving using the quadratic formula x = +-4
see the attached figure to better understand the problem
we know that
In a parallelogram opposite angles are congruent, and consecutive angles are supplementary
So
in this problem
∠Y=
°
∠W=∠Y
∠W=°
∠Z=∠X
∠Y+∠Z=
°
∠Z=
∠Z=
°
∠X=∠Z
∠X=°
therefore
the answer is
∠Y=°
∠W=°
∠X=°
∠Z=°
A must be parallel to b.
Proof:
∠3 = <span>∠13 (given)
</span>∠15 = <span>∠13 (vertically opposite angles are equal)
Since </span>∠13 = ∠3 and ∠13 = ∠15, ∠15 = <span>∠3
Then, a must be parallel to b (transverse line d cuts parallel lines producing converse alternate angles that are equal (ie </span>∠15 = <span>∠3))
</span>
