Create and Solve an equation to find the unknown angle.

valentina_108 [34]

Answer:

Equation: 2x + 3x + 10 = 180

x = 34

Top angle = 68 degrees

Bottom angle = 112 degrees

Step-by-step explanation:

The two angles add to 180, so set them equal to 180.

2x + 3x + 10 = 180

5x + 10 = 180

- 10 - 10

5x = 170

/ 5 / 5

x = 34

Plug x into angles,

2(34) = 68

3(34) + 10 = 112

Answer:

Option D doesn't make any sense.

Step-by-step explanation:

D) 7 hours of sleep correspond to an age of 19 years.

That is wrong.

If we use the expression provided

hours = 8 + 0.5*(18 -age)

hours = 8 + 0.5*(18 -19)

hours = 8 + 0.5*(-1)

hours = 7.5

Find the distance between the points (-5, 0) and (-4, 1).

choli [55]

The formula of a distance between two points A and B is :

$AB=\sqrt{(x_{B}- x_{A})^2 +( y_{B}- y_{A})^2 }$

You should this formula by heart.

Then, you just have to apply it ! :D

Here :

$x_{A}=-5$
$y_{A} =0$

$x_{B} =-4$
$y_{B}= 1$

Therefore :

$\sqrt{(-4-(-5))^2+(1-0)^2}$
$= \sqrt{1^2+1^2}$
$= \sqrt{1+1}$
$= \sqrt{2}$

In short, the answer would be the first option : $\sqrt{2}$ .

Hope this helps !
