Which side lengths form a right triangle?<br> Choose all answers that apply:
kkurt [141]

Answer:

All 3 are right triangles.

Step-by-step explanation:

In a right triangle c^2 = a^2 + b^2   where c is the longest side.  ( by Pythagoras).

a) 3^2 = 9, 6^2 = 36 and √27 ^ 2 = 27

36 = 9 + 27

So this is a right triangle.

b)

17^2 = 289, 15^2 = 225 and 8^2 = 64

289 = 225 + 64

Also right triangle.

c) √50 ^ 2 = 50, 5^2 = 25 and 5^2 = 25

So also right triangle.

What is the value of c?<br> 14 = - 2c - 6 - 3c
Neporo4naja [7]

Answer:

c = -4

Step-by-step explanation:

Step 1: Write equation

14 = -2c - 6 - 3c

Step 2: Solve for <em>c</em>

  1. Combine like terms: 14 = -5c - 6
  2. Add 6 on both sides: 20 = -5c
  3. Divide both sides by -5: c = -4

Step 3: Check

<em>Plug in c to verify it's a solution.</em>

14 = -2(-4) - 6 - 3(-4)

14 = 8 - 6 + 12

14 = 2 + 12

14 = 14
