Lines a and b are parallel. When they are cut by transversals, they form a triangle Parallel lines a and b are cut by transversa

lord [1]

Answer:

Therefore, the angle 3 have 28 degrees.

Step-by-step explanation:

We know that the lines a and b are parallel. When they are cut by transversals, they form a triangle. Parallel lines a and b are cut by transversals s and t to form a triangle. Angle 1 is 90 degrees, angle 2 is 62 degrees.

We know that the number of degrees in a triangle equals 180.

We get:

$90+62+x=180\\\\152+x=180\\\\x=180-152\\\\x=28\\$

Therefore, the angle 3 have 28 degrees.

Which two values of x are roots of the polynomial below?<br> x2 + 5x+7

Dmitry [639]

Answer:

The roots are

$x=\frac{-5+i\sqrt{3}}{2}$ and $x=\frac{-5-i\sqrt{3}}{2}$

Step-by-step explanation:

we have

$x^{2} +5x+7$

To find the roots equate the polynomial to zero and cmplete the square

$x^{2} +5x+7=0$

$x^{2} +5x=-7$

$(x^{2} +5x+2.5^{2})=-7+2.5^{2}$

$(x^{2} +5x+6.25)=-0.75$

rewrite as perfect squares

$(x+2.5)^{2}=-0.75$

take square root both sides

$(x+2.5)=(+/-)\sqrt{-\frac{3}{4}}$

Remember that

$i=\sqrt{-1}$

substitute

$(x+2.5)=(+/-)i\sqrt{\frac{3}{4}}$

$(x+\frac{5}{2})=(+/-)i\frac{\sqrt{3}}{2}$

$x=-\frac{5}{2}(+/-)i\frac{\sqrt{3}}{2}$

therefore

The roots are

$x=\frac{-5+i\sqrt{3}}{2}$

$x=\frac{-5-i\sqrt{3}}{2}$
