Answer:

Answer: 50 degrees

Step-by-step explanation:

<h3>important things to know:</h3>

the square in the bottom right means 90°

all angles in a triangle add up to 180°

using this knowledge, you can make the following equation:

90 + 40 + x = 180

130 + x = 180

now subtract 130 from both sides.

x = 180 - 130

x = 50°

Dan factored x^2+121 into (x+1-11)

babunello [35]

Answer:

Your question is a little unclear. If you are just trying to factor x² + 121, it's prime. (can't be factored using real numbers).

Step-by-step explanation:

The difference of two squares is a special form. a² - b² = (a+b)(a-b).

But, the sum of two squares is prime. a²+ b² cannot be factored.

On a coordinate plane, parallelogram P Q R S is shown. Point P is at (negative 2, 5), point Q is at (2, 1), point R is at (1, ne

Anika [276]

Answer:

The perimeter of parallelogram PQRS = $2\sqrt{10}+8\sqrt{2}$ ⇒

2nd answer

Step-by-step explanation:

* Lets revise some properties of the parallelogram

- Each two opposite sides are parallel

- Each two opposite sides are equal

- Its perimeter is the twice the sum of two adjacent sides

* Lets solve the problem

∵ PQRS is a parallelogram

∵ The length of side SR is $4\sqrt{2}$

∵ The length of side QR is $\sqrt{10}$

∵ SR and RQ are two adjacent sides

∵ The perimeter of parallelogram PQRS = 2(RQ + SR)

∴ The perimeter of parallelogram PQRS = $2(\sqrt{10}+4\sqrt{2})$

∵ $2*\sqrt{10}$ = $2\sqrt{10}$

∵ $2*4\sqrt{2}$ = $8\sqrt{2}$

∴ The perimeter of parallelogram PQRS = $2\sqrt{10}+8\sqrt{2}$
