Which group of three squares will form a right triangle when<br> joined at their vertices?
Ilia_Sergeevich [38]

Answer:

Option ?) 17 cm, 15 cm, 8 cm

<em>The assignment should have </em><em>four options</em><em> to choose from, but there is only a picture of two. </em>

Step-by-step explanation:

<em>None of the squares </em><em>shown</em><em> form a right triangle. To determine if sides form a right triangle, you use </em><em>this</em><em> formula:</em>

a²+b²=c²

<em>We are given two options in the picture.</em>

Option A) 18, 10, and 8.

Option B) 12, 9, and 6.

<em>So, now we need to apply the formula:</em>

Option A)

║8² + 10² = 18²

  ↓

║64 + 100 = 324

  ↓

║FALSE

Option B)

║6² + 9² = 12²

  ↓

║36 + 81 = 144

  ↓

║FALSE

<em>Both of these options are false.</em><em> But, I decided to look up this assignment to check my answer. It turns out, there are </em><em>4 options</em><em>, and you only had a picture of two. So, what's the answer?</em>

<em />

<em>There is an answer choice that shows 3 squares with the lengths of 17 cm, 15 cm, and 8 cm. </em><em>This is the correct answer</em><em>.</em>

<em />

<em>For proof, let's apply the formula:</em>

Option ?)

║8² + 15² = 17²

  ↓

║64 + 225 = 289

  ↓

║TRUE

<em>[Since the option isn't shown, I'll put a '?' so there is no confusion]</em>

Mary is flying a kite and has let out 50 yards of kite string. Mary’s kite is directly above Erika.
ch4aika [34]

The distance of Erika from kite directly is 35.71 yards

Step-by-step explanation:

Considering the given situation as a right triangle with string as hypotenuse and the distance between both girls as base

So,

h = 50\ yards\\b = 35\ yards

As the triangle is a right triangle, we can use pythagoras theorem to solve this problem.

h^2 = b^2 + p^2\\p^2 = h^2 - b^2\\p^2 = (50)^2 - (35)^2\\p^2 = 2500-1225\\p^2 = 1275\\\sqrt{p^2} = \sqrt{1275}\\p = 35.707\ yards

Rounding off to nearest hundredth

=> 35.71 yards

Hence,

The distance of Erika from kite directly is 35.71 yards
