First to answer get brainliest thankss :)

Step-by-step explanation:

Given:

With the above info, we can find Angle 1.

We know that Angle 1 + Angle 2 + Angle 3 = 180 Degrees

Let's substitute the above info into our equation.

Angle 1 + 180 - 104 + 57 = 180

=> Angle 1 + 133 = 180

=> Angle 1 = 47 degrees.

Kind request: Please give me brainliest.

47

Step-by-step explanation:

First, we find angle 2. It is a supplementary angle with that 104 exterior so we take 180-104=76. Angle 2 is 76.

Now that we have two angles of the triangle, we can set up the equation:

76+57+x=180

we have 180 because all three angles of any triangle equal 180.

solving for x:

simplify the equation, (x)+(76+57)=180

combine like terms, x+133=180

Subtract 133,  180−133=47

x=47.

step-by-step explanation:

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
