Can someone tell me what side b is? Thank youuu

The answer is

Step-by-step explanation:

To find side b we use sine

sin ∅ = opposite / hypotenuse

From the question

side c is the hypotenuse and

side b is the opposite

side c = 60m

B is 69°

So we have

sin 69 = b/c

sin 69 = b / 60

b = 60 sin 69

b = 56.0148

b = 56. 01m to 2 decimal places

Hope this helps you

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
