Answer:
A
Step-by-step explanation:
is in the fourth quadrant where tan < 0
The related acute angle = 2π -
= 
Hence
tan(
)
= - tan(
)
= - 
= -
× 
= -
→ A
Answer is
U= (-2,2)
V=(-2,4)
W= (-4,3)
Step by step
Find points for the triangle.
Using the rule for reflection across y axis.
The rule for a reflection over the y -axis is (x,y)→(−x,y)
U (2,2) ➡️ (-2,2)
V (2,4) ➡️ (-2,4)
W (4,3) ➡️ (-4,3)
B. 13
12^2 + 5^2 = c^2
169 = c^2
13 = c
please mark as brainliest :D
K = y/x OR y = kx
hope it helps!
Answer:
they work together, it will take 2.4 hours to build the wall.
Step-by-step explanation:
One bricklayer can build a wall in 6 hours.
One hour work = 
Another bricklayer can build the same wall in 4 hours.
One hour work = 
They can together, how long will take them to build the wall.
Let's take "t" the time taken to build the wall.
The sum of their work rate = 1 (To build the wall)

Now we have to solve this equation. Take LCD of 6 and 4.
The LCD (least common divisor) of 6 and 4 is 12.

5t = 12*1
5t = 12
Dividing both sides by 5, we get
t = 
t = 2.4 hours.
So, they work together, it will take 2.4 hours to build the wall.
