Question

I need help........ PLEASE HELP!!!!!!!!!!!!!!! This is confusing me.... I don't understand it. I really need help with this. If the measures of the angles in the following triangle were listed in increasing order, which measure would be second? The figure is not drawn to scale.

Answer 1

Explanation:

We know that a triangle equals to 180 degrees.

(2x+24)+(4x+43)+(x^2+1)=180

the awnser to this is x=8.

You plug in 8 into x

Angle 1: 2(8+24) --> 40

Angle 2: 4(8+43) -->75

Angle 3: (8^2+1) -->65

Check your work: add values together 40+75+65=180
