Remember, all inside angles in a triangle add up to 180°

So:

3x+5x+7+x+2=180

Combine like terms

9x+9=180

Subtract 9 from both sides

180-9=171

9x=171

Divide by 9 on both sides

171/9=19

x=19

Plug it into all the angle measures.

Angle X: x+2, 9+2=11, Angle X=11°

Angle Y: 5x+7, 5(9)+7=52, Angle Y=52°

Angle Z: 3x, 3(9)=27, Angle Z=27°

Ann made a 33-step staircase using 1818 toothpicks as shown in the figure. How many toothpicks does she need to add to complete
malfutka [58]
You would take 1818÷33=55.09

55.09 is how many toothpicks it took for each step made

Then you would take 55.09×55=3029.95

You can make sure this is correct by taking 55.09×33=1817.97 which would actually be 1818 because you had to round it up
