Answer:

x = 9

Step-by-step explanation:

Since we know that the triangle is a right triangle we also know that the angle would be 90 degrees

However we are only given 56 and 3x+7

Let 3x+7 be u

We know that 56+u=90 so solve for u

u=90-56

u = 34

Now u = 3x + 7 so,

3x + 7 = 34

solve for x,

3x=34-7

3x=27

x=27/3

x=9.

FIND PR.PLS HELP BRAINLIEST...
slega [8]

Answer:

6.2 units.

Step-by-step explanation:

We are given two angles and an opposite corresponding side. To solve for an unknown side, we can use the law of sines.

\frac{8}{sin(90)}=\frac{x}{sin(180-39-90)}=\frac{x}{sin(51)}

Cross multiplying and solving will get you this:

x=\frac{8(sin(51))}{sin(90}

Which can simplify to:

x=8(sin(51))

Which putting into a calculator gets you:

x=6.2

So the line PR is 6.2 units long.

Consider that the roots of a cubic equation with integral coefficients are 1, −2, and 3.
Iteru [2.4K]

Answer:

The answer is option A) X + 2

Step-by-step explanation:

Any polynomial of order n can be expressed in terms of their roots in factors of the form

(x-a)(x-b)(x-c)(x-d)....... = 0

Where a,b,c,d,... are the roots of the polynomial

In the example shown

(x+2) = (x-(-2))

And -2 happens to be the root of the polynomial in question
