A triangle has three sides: a, b, and c. Side a = 72 feet, and side b = 154 feet, and side c = 170 feet. True or false: this tri

Juliette [100K]

Answer:

True

Step-by-step explanation:

If the triangle was a right angled triangle then we can prove it using the Pythagoras theorem: c² = a² + b²

c is the largest side and a and b are the two smaller sides of the triangle.

So if this is true then √72² + 154² should be 170:

170² = 72² + 154²

28900 = 5184 + 23716

28900 = 28900

So we have proved using Pythagoras theorem that the triangle is a right angled triangle.

Tell weather the lines for each pair of equations are parallel perpendicular or neither y=-1/5x+6

FinnZ [79.3K]

Answer:

The slopes are neither perpendicular nor parallel.

Step-by-step explanation:

First we are going to find the slope-inercept form from the equation, -2x + 10y = 5.

Solve for y.

-2x + 10y = 5

+2x. = +2x

10y = 2x + 5

$\begin{gathered} \frac{10y}{10} = \frac{2x + 5}{10} \\ y = \frac{1}{5}x + \frac{1}{2} \end{gathered}$

So we now have

$\begin{gathered}y = \frac{1}{5}x + \frac{1}{2} \\ and \\ y = - \frac{1}{5} x + 6 \end{gathered}$

Looking at the equation above, the slopes are neither perpendicular nor parallel.

Which pairs are like terms in expression 2/5y + 1/5x - 0.2y - 6 + (-2)

Gelneren [198K]

The pair of like terms are:

$\frac{2}{5}y \text{ and } -0.2y$

Solution:

Given expression is:

$\frac{2}{5}y + \frac{1}{5}x -0.2y-6+(-2)$

We have to find the pairs that are like terms in the given expression

Like terms means that, terms that have same varibale but different ( or same ) coefficients

Here in the given expression "x" and "y" are the two variables present

Arrange the like terms

$\frac{2}{5}y-0.2y+\frac{1}{5}x-6+(-2)$

So here the first two terms has same varibale "y" but different coefficients. So they form a pair of like terms

"x" is present only once . There is no other term with variable "x"

6 and -2 are constants

So the pair of like terms are: $\frac{2}{5}y \text{ and } -0.2y$
