8

²

=

36

+

64

=

100

We now calculate the square of the biggest side :

10

²

=

100

They are equal, and thus, the triangle is a right triangle.

What is -2 sqrt 50 - sqrt 125 in simplest radical form
Gnoma [55]

Answer:

- 10√2 - 5√5

Step-by-step explanation:

- 2√50

√50 = √( 2 x 5 x 5 ) = 5√2

- 2√50

= - 2 x 5√2

= - 10√2

- √125

= - √( 5 x 5 x 5 )

= - 5√5

- 2√50 - √125

= - 10√2 - 5√5

What is the x-intercept for the equation -2x + 5y = -10
Zielflug [23.3K]

Answer:

The x-intercept is at the point (5,0).

Step-by-step explanation:

-2x + 5y = -10

At the x intercept y = 0 so we substitute y = 0 into the given equation:

-2x + 5(0) = -10

-2x = -10

x = 5.

The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is five times
Art [367]

Answer: 30°, 67° e 83°.

Step-by-step explanation: The angles are (2x + 16)/5 , x e x + 16°

Adding all the angles, comes:

(2x + 16)/5 + x + x + 16° = 180° ;

2x + 16° + 5x + 5x + 80° = 900° ;

12x = 900° - 16° - 80° ;

12x = 804°° ;

x = 804°/12 ;

x = 67°

So, the first angle is (2,67 + 16)/5 = 30°, the second is 67° and the third is 83°.
