Answer:

30 degrees

Step-by-step explanation:

Since 4 is equal on the other side of 2, it would be congruent, which is the same as 2. So, 30 degrees.

Answer:the length of the third side is 4√7

Step-by-step explanation:

The perimeter of a triangle is 16 to the square root of 7 feet. This is expressed as

Perimeter = 16√7 feet

The perimeter of a triangle is the sum of the length of the three sides of the triangle.

If the two sides measure the square root of 343 feet and the square root of 175, which are expressed as √343 and √175, the third length would be

16√7 - (√343 + √175)

Expressing √343 as a radical, it becomes 7√7

Expressing √175 as a radical, it becomes 5√7

7√7 + 5√7 = 12√7

Therefore, the third length would be

16√7 - 12√7 = 4√7 feet

<h3>Question :-</h3>

Is (x-2) is a factor of x³-3x²-x +7 –

Yes
No ☑

<h3>Explanation :-</h3>

We are given –

Polynomial function, P(x) = x³-3x²-x +7

In order to check if x - 2 is a factor of x³-3x²-x +7 or not, we must show that P(2) = 0.

Let's find value of x!

$\qquad$ $\twoheadrightarrow\bf P(x) = x³-3x²-x +7$

$\qquad$ $\twoheadrightarrow\bf Q(x) =x - 2$

$\qquad$ $\twoheadrightarrow\bf If \:Q(x) = 0$

$\qquad$ $\twoheadrightarrow\bf x - 2 = 0$

$\qquad$ $\twoheadrightarrow\bf x = 2$

Now Put x = 2 into the polynomial –

$\qquad$ $\purple{\twoheadrightarrow\bf P(2) = 2³-3(2)²-2+7}$

$\qquad$ $\twoheadrightarrow\sf P(2) = 8 - 3 \times 4 +5$

$\qquad$ $\twoheadrightarrow\sf P(2) = 8 -12 +5$

$\qquad$ $\twoheadrightarrow\sf P(2) = 13-12$

$\qquad$ $\purple{\twoheadrightarrow\bf P(2) =1 }$

Since the value of the polynomial function st x = 2 is not Zero (0). Henceforth, ( x - 2) is a factor of x³-3x²-x +7.
