The sum of three consecutive numbers is 72 what are the smallest of these numbers
Airida [17]
A + b + c = 72

a = b - 1

c = b + 1

 

(b - 1) + b + (b + 1) = 72

Simplify

3b = 72

b = 24

 

a = 24 - 1

a = 23

Please help worth a lot of points !!!<br><br> Find the measure of show your work
VashaNatasha [74]

Answer:

<u>∠AEB = 72°</u>

Step-by-step explanation:

<u>Finding x</u>

  • ∠AEB = ∠DEC (Vertically opposite angles)
  • 7x - 5 = 2(4x - 8)
  • 7x - 5 = 8x - 16
  • 8x - 7x = -5 + 16
  • x = 11

<u>Finding ∠AEB</u>

  • 7x - 5
  • 7(11) - 5
  • 77 - 5
  • <u>∠AEB = 72°</u>

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>
