1. If Salwa constructs a triangle using her protractor, and the first two angles she constructed were 55° and 105°, what will the third angle be
when she is done?
80°
30°
20°
55

20°

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

Angle 1 = 55°

Angle 2 = 105°

The sum of the three interior angles of a triangle is always 180°.

So:

180 = 55+105 + x

Where x is the missing angle.

Solving for x:

180-55-105 =x

20°=x

Feel free to ask for more if needed or if you did not understand something.

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

answer: 0.26
