Is the triangle a right triangle? 4 6 7 Is this a right triangle?

Bingel [31]

Answer:

Step-by-step explanation:

Given :-

A triangle with some side measure .
The sides are 4 ,6,7.

And we need to tell whether it is a right angled triangle or not . It will be a right angled triangle if it follows the Pythagoras Theorem.

Pythagoras Theorem :-

In right angle triangle the sum of squares of the two smallest sides is equal to the square of the largest side .

Here the two smallest sides are 4 & 6 .

Sum of Squares of 4 and 6 :-

$:\implies$ 4² + 6²

$:\implies$ 24 + 36

$:\implies$ 60

Square of 7 :-

$:\implies$ 7²

$:\implies$ 49

And :-

They aren't equal. So the triangle is not a right angled triangle .

Hence the triangle is not a right angle triangle.

Translate the sentence into an equation using n to represent the unknown number. Then solve the equation for n.

Kitty [74]

Answer: a.

Step-by-step explanation:

46 is subtracted by n to get -21 so the equation is 46 - n = -21

Add n on both sides; 46 - n + n = -21 + n; 46 = -21 + n

Add 21 on both sides; 46 + 21 = -21 + n + 21; 67 = n

So n = 67
