Answer:
No.
Step-by-step explanation:
In order to complete the square, you need to have the x values together, not the constant.
To complete the square <em>correctly </em>you would need to have x² - 20x = -6 and continue from there; divide 20 by 2 and square the result to get (x - 10)² = 96.
Answer:
∠Q = 53.13 degrees
Step-by-step explanation:
Given that ∆PQR, ∠P = 90degrees , this means that the triangle is a right angled triangle
Hence using the notation
SOH CAH TOA
where S is sine, C is cosine, T is tangent and O, A and H represents the size of the opposite, adjacent and hypotenuse sides
Considering ∠Q and the given sides
PR=16cm is the opposite side,
PQ= 12 cm is the adjacent side hence we use TOA
Tan Q = 16/12 =
Q = Arc tan 16/12
= 53.13 degrees
Answer:
they are all even numbers except for 155
Step-by-step explanation:
Answer:
Y || Z
Step-by-step explanation:
We know that Y⊥B, and Z⊥B, which means both Y and Z are perpendicular to B, meaning that they both create 90° angles with B, and from that, we can make the conclusion that Y || Z
