Answer: -1
Step-by-step explanation:
First change tan(315) to:

Then evaluate the sine and cosine function. What is the y component of 315 degrees? What is the x component of 315 degrees?

The equation for finding the hypotneus of a right triangle is

so we know that 4²+b²=5²
so that would simplify as 16+b=25
so x=25-16
which is 9
so therefore we can conclude that
Answer:
the first box can be filled by,

the second box can be filled by,

Answer: The pair of corresponding angles are ∠2 and ∠14 , ∠3 and ∠7 . Option (B) and (D) is correct . When two lines are parallel to each other and cross by another line i.e is called the Transversal , the angles lies in the matching corners are called corresponding angles.

Answer:
<A = 41.4°
Step-by-step explanation:
Recall, SOH CAH TOA
Reference angle = <A
Hypotenuse length = 8
Adjacent length = 6
Since Hypotenuse and Adjacent are involved, we would apply CAH, which is:
Cos A = Adj/Hyp
Plug in the values
Cos A = 6/8
Cos A = 0.75

A = 41.4096221° ≈ 41.4° (nearest tenth)
