A triangle has sides with lengths of 6 miles, 14 miles, and 15 miles. Is it a right triangle?
maks197457 [2]

Answer:

the triangle is not right angled traingle

Step-by-step explanation:

For a right angle triangle

a^{2} + b^{2} = c^{2}   where a is the base , b is the height and c is the hypotenuse

taking a= 6 b = 14 and c = 15

hence 6^{2} +14^{2} = 15^{2}

         36+196 = 232 which is not equal to 225

therefore the triangle is not right angled traingle

Solve each inequlity 5- 2( 3x-4) -2x &lt; -6x + 4
almond37 [142]

Answer:

x > 9/2

Step-by-step explanation:

don't get scared :) we can isolate the variable easily!

distribute

5 -2( 3x-4) -2x < -6x + 4

5 -6x + 8 - 2x < -6x + 4

-8x + 13 < -6x + 4

+6x   -13   +6x   -13

-2x < -9

x > 9/2

change the direction of the sign because we divided by a negative

There you go!

I hope this helps (:
