Hello i need i do not understand this at all. try to would be

reflecting over y=x would only be its self if that line was a axis of symmetry.

In this case it is not so we can eliminate any answer with y=x so we have two answers left B and D

and since there are 4 quadrants it would need to reflect 4 times

so the answer is D

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
