A triangle has sides with lengths of 6 yards, 14 yards, and 19 yards. Is it a right triangle?

NO

Step-by-step explanation:

to work this out, you will need to use the Pythagoras theorem. This only works for a right triangle so it will prove if this is a right angle.

Pythagoras Theorem:

a and b are the two smaller sides (6 and 14 yards)

c is the largest side (19 yards)

to calculate this, place the lengths of sides a and b into the equation:

the formula states that the answer (232) is the length of side c squared. to calculate just the length of c, we need to square root 232.

this is NOT equal to 19 yards (the length of side c) therefore this NOT a right triangle as the Pythagoras theorem only works for right triangles

I HOPE THIS WAS HELPFUL :-)

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
