What is angle A on a right triangle with sides AB being 6 and side CB being 4

41.8

Step-by-step explanation:

a=4

c=6

C=90

Applying sine rule :

a/sinA = c/sinC

4/sinA=6/sin90 sin90=1

4/sinA=6/1

Cross multiplying we get

4 x 1=6 x sinA

4=6sinA

divide both side by 6

4/6=(6sinA)/6

4/6=sinA

sinA=4/6

A=sin(inverse)(4/6)

A=41.8

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
