Answer:

x=13

Step-by-step explanation:

Switch sides:

2x−9=17

Add 9 to both sides:

2x−9+9=17+9

Simplify

2x=26

Divide both sides by 2:

2x/2 =26/2

Simplify to get the result.

x=13

Given the following triangle side lengths, identify the triangle as acute, right or obtuse. Show your work.

Shkiper50 [21]

Let "a", "b" and "с" be sides of the triangle ("с" is the longest side).
The triangle will be:

right if a² + b² = c²
аcute if    a² + b² > c²
obtuse if   a² + b² < c²

a.
a=3, b=4 and c=5

a² + b² = 3² + 4² = 9 + 16 = 25 and c² = 5² = 25

25 = 25 ⇒ right triangle.

b.
a=5, b=6 and c=7

a² + b² = 5² + 6² = 25 + 36 = 61   and c² = 7² = 49

61 > 49 ⇒ аcute triangle.

c.
a=8, b=9 and c=12

a² + b² = 8² + 9² = 64 + 81 = 145   and c² = 12² = 144

145 > 144 ⇒ аcute triangle.
