The smallest angle of a right triangle is 20-degree angle. What is the measure of the medium angle?

Veronika [31]

Answer:

70 degrees.

Step-by-step explanation:

Hello!

It says that this triangle is a right triangle. That means one angle is 90°. Since there are 180° in a triangle, all we have to do is subtract 90 + 20 from 180.

90 + 20 = 110

180 - 110 = 70.

So the medium angle is 70°.

Hope this helps!

Use the quadratic formula to determine the exact solutions to the equation.

Ilia_Sergeevich [38]

ANSWER

$x = \frac{5}{4} - \frac{ \sqrt{ 17} }{4}$

$x = \frac{5}{4} + \frac{ \sqrt{ 17} }{4}$

EXPLANATION

The given equation is:

$2 {x}^{2} - 5x + 1= 0$

Comparing this to

$a {x}^{2} + bx + c = 0$

we have a=2, b=-5, c=1

The quadratic formula is given by

$x = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac} }{2a}$

We substitute the values to get,

$x = \frac{ - - 5 \pm \sqrt{ {( - 5)}^{2} - 4(1)(2)} }{2(2)}$

$x = \frac{ 5 \pm \sqrt{ 17} }{4}$

$x = \frac{5}{4} - \frac{ \sqrt{ 17} }{4}$

$x = \frac{5}{4} + \frac{ \sqrt{ 17} }{4}$
