In ▵PQR, PR is extended through point R to point S, m
alexgriva [62]

Answer:

x = 10

Step-by-step explanation:

Here, we are tasked with calculating the value of x.

To do this, we need the picture of the wordings given in the question.

please check the attachment for a pictorial representation.

Now the theorem to use is that , the exterior angle of a triangle is equals the sum of the two opposite interior angle.

Thus, mathematically;

3x + 11 + 3x + 15 = 10x -14

6x + 26 = 10x -14

10x-6x = 26 + 14

4x = 40

x = 40/4

x = 10

Shtirlitz [24]

Answer:

area = 2.54 {ft}^{2}

Step-by-step explanation:

The formula to find the area of a circle is

area \: of \: circle \:  = \pi {r}^{2}

Let pi be (3.14), the radios as given in the question is (0.9). Therefore;

\pi {r}^{2}  =  \\ (3.14) \: {(0.9)}^{2}  \\ 3.14 \times 0.81 =  \\ 2.5434 \: or \: 2.54 {ft}^{2}

Plzzzzz help will give brain and points!!! Explain why a quadratic equation with a positive discriminant has two real solutions,
NISA [10]

Answer:

The given equation is -2x^2 = -8x + 8

This can be rewritten as 2x^2 - 8x + 8 = 0

Here the value of a =2, b = -8 and c = 8

Discriminant = b^2 - 4ac

Now plug in the above values in the discriminant, we get

= (-8)^2 - 4*2*8

= 64 - 64

= 0

Here the discriminant is 0, so we will get one real root.

The discriminant is equal to 0, which means the equation has one real number solution.

Hope this will helpful.

Thank you.
