BEST GETS BRAINLIST! 16 POINTS! Help please, attached below, please do a step by step of The SohCahToa method. I help to find the height, round to the nearest hundred decimal.

Perimeter of ΔABC = 16.46 units

Step-by-step explanation:

By applying cosine rule (CAH) in the given triangle ADB,

cos(∠BAC) =

cos(55°) =

AB = 5.23 units

Since, ΔABC is an isosceles triangle

AB = BC = 5.23 units

AD = DC = 3 units [Perpendicular drawn from a vertex of an isosceles triangle is a perpendicular bisector of the opposite side]

Therefore, AC = AD + DC = 6 units

Now perimeter of ΔABC = AB + BC + AC

                                          = 5.23 + 5.23 + 6

                                          = 16.46 units

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

each side has a different length.
