A triangle has side lengths 32, 45 and 18. What type of triangle is it?

sergejj [24]

Answer:

Part A) Option C. obtuse

Part B) Option B. acute

Step-by-step explanation:

we know that

Applying the Pythagoras Theorem

if $c^{2}=a^{2}+b^{2}$ ----> is a right triangle

if $c^{2}>a^{2}+b^{2}$ ----> is an obtuse triangle

if $c^{2}$ ----> is an acute triangle

where

c is the greater side

Part A) A triangle has side lengths 32, 45 and 18. What type of triangle is it?

we have

$c^{2}=45^{2}=2,025$

$a^{2}+b^{2}=32^{2}+18^{2}=1,348$

therefore

$c^{2}>a^{2}+b^{2}$

Is an obtuse triangle

Part B) A triangle has side lengths 44, 36 and 30. What type of triangle is it?

we have

$c^{2}=44^{2}=1,936$

$a^{2}+b^{2}=36^{2}+30^{2}=2,196$

therefore

$c^{2}< a^{2}+b^{2}$

Is an acute triangle

Which equations are true?<br>A: -x = -x + x + 0<br>B: -x = 0 + (-x)<br>C: None Of The Above

Leto [7]

Answer: B
Explanation: if you look at A and try to combine like terms, you will add the -x on the right side the the one on the left, cancelling out the x on the left. then you have 0=x+0, and unless x=0, it is not true.
With B, when you add x to the -x, you cancel it out, giving you 0=0, which is true. hope it helps!
