Answer:
Step-by-step explanation:
Let,

Using the formula:

Yes because all sides are equal so take one side and multiply by it by 3 and thats ur anwaserr
Point-slope form : y-y₁=m(x-x₁)
Passes through (6, 1) and parallel to a line with slope of -3.
Simply plug everything in.
*m =slope
y - y₁=m(x-x₁)
y - 1 = -3(x - 6)
Simplify.
y - 1 = -3x + 18
Add 1 to both sides.
y = -3x + 19

Answer:
, 
Step-by-step explanation:
Part a) Find the sin(A)
we know that
In the right triangle ABC
----> the sine of angle (A) is the opposite side angle (A) divided by the hypotenuse
substitute the values

Part b) Find the cos(A)
we know that
In the right triangle ABC
----> the cosine of angle (A) is the adjacent side angle (A) divided by the hypotenuse
substitute the values
