Answer:

x = 89°

Explanation:

The angles inside a triangle will always add up to 180°

49 + 42 = 91

180 - 91 = 89°

X = 89

A triangle always equals 180°. Because two out of three angles are given, the two known angles (42° and 49°) can be added together which is 91°. The 91° can be subtracted from 180° to find the unknown angle x.

The graph of a function f(x)=5to the power of x -5 contains the point (2,y) what is the value of y
Mila [183]

I believe this this the function.

f(x) =  {5}^{x - 5}

then

f(x) =  {5}^{2 - 5}

then

f(x) =   {5}^{ - 3}

then

y =  \frac{1}{125}
