Use the pythagorean Theorem to prove the three sides of the triangle are the three sides of a right triangle. Show all of your w
weeeeeb [17]

Answer:

2^{2} + (2\sqrt{3}) ^{2} = 4 + 4 * 3 = 16 = 4^{2}

Step-by-step explanation:

The Pythagorean Theorem states that the two shorter sides of a right triangle squared and added together will equal the longest side (hypotenuse) of the right triangle squared. The longest side of this right triangle is 4, 4 squared is 16. The two shorter sides of the right triangle are 2 and 2\sqrt{3}, squared individually would be 4 and 12, and added together they also equal 16. These sides are a valid input for the Pythagorean Theorem, so these three sides are the sides of a right triangle. 2 and 2\sqrt{3} being the legs of the right triangle, and 4 being the hypotenuse.

9.      1/3+(x+20)+(x-10)+40=360           10.   1/2x+1/2x+(x-15)+(x-25)+100=540

          1/3+2x+50=360                                  4x+60=540

          (3/1) 1/3+2x=300(3/1)                           4x/4=480/4

          2x=300                                                X=120

A recipe calls for 2/5 cup of sugar for every 8 teaspoons of vanilla. What is the unit rate in teaspoons per cup ?
tamaranim1 [39]
For 2/5 cup, vanilla needed = 8 teaspoons
so, for 1 cup, it would be: 8 / 2/5
⇒8 × 5/2
⇒40/2
⇒20

In short, Your Answer would be 20 teaspoons

Hope this helps!
