According to Triangle Inequality Theorem,

adding ANY two sides (together) of a triangle must be GREATER than the third side.

Meaning, two sides CANNOT be less than the third side andCANNOT be equal to the third side.

Because when you add 3 and 16, you get 19.

19 is EQUAL to the third side, 19. This BREAKS the condition of the theorem.

ANSWER: No, the triangle cannot have the lengths of 3,16, and 19.

Which equation is equivalent to 3 = 87 - h?

kow [346]

Answer:

h = 84

h + 3 = 87 (Add h to both sides)

h = 84 (Subtract 3 from both sides)

A triangle has sides with lengths of 60 feet, 63 feet, and 87 feet. Is it a right triangle?

Sedaia [141]

Answer:

Yes

Step-by-step explanation:

We can use the Pythagorean Theorem to check if this triangle is a right triangle:

$a^2+b^2=c^2$

Note that $a$ and $b$ are the legs of the triangle and $c$ is the hypotenuse:

Substitute the lengths of the sides into the equation:

$60^2+63^2=87^2$

$3600+3969=7569\\7569=7569$

Therefore this triangle is a right triangle.

Shaun plotted a point on the number line by drawing 5 equally spaced marks between 0 and 1 and placing a point in the third mark

SIZIF [17.4K]

If it is 5 equally spaced marks, then each mark represents 1/6

0 -- 1/6 -- 2/6 -- 3/6 -- 4/6 -- 5/6 -- 1

so the third mark would represent 3/6 which reduces to 1/2

What + 89= 9(6+5) please solve for my answer and explain how you got your answer

nlexa [21]

The answer would be 10.

6 + 5 = 11
11 x 9 = 99

This means 9(6+5) = 99

99 - 89 = 10
