Step-by-step explanation:

Here

With reference angle 45°

hypotenuse (h) =x

perpendicular (p) = 5

Let

Sin45° = p/h

1/√2 = 5/ x

therefore x = 5√2

Now

b=?

Using Pythagoras theorem

b² = h² -p²

b² = (5√2)² - 5²

b² = 50 - 25

b² = 25

b² = 5²

Therefore b = 5

Now

tangent = p/b = 5/5 = 1

What is the point-slope form of an equation passing through (0, -5) with a 5 points
Novay_Z [31]

Answer:

y=2x-5

Step-by-step explanation:

y-y_{1}=m(x-x_{1})

x_{1}=0, y_{1}=-5\\, and m=2

y-(-5)=2(x-0), -(-5)-Two negatives make it positive, and you distribute the 2

y+5=2x, you now subtract 5 to get y by itself to get your answer of

y=2x-5

*NOTE* (0,-5) is the y-intercept, so you could have used the linear equation of y=mx+b, m=2, and b(y-intercept)=-5

giving you y=2x-5
