The measures of all of the interior angles of a triangle are in the extended ratio 1 : 2 : 3. The value of the smallest angle is

1 answer:

7 0

The sum of the interior angles of a triangle is 180°.

Let's suppose that all 3 angles in the ratio are divisible by a value x.

So the three angles become 1x, 2x and 3x.

1x + 2x + 3x = 180°

6x = 180°

x = 30° [ By dividing both sides by 6 ]

Thus the three angles are: 1x = 30° ; 2x = 2*30 = 60° ; 3x = 3*x = 90°

Hence the smallest angle is 30°.

Find the distance between the points (1, 7) and (10, 1)<br> Please help:)

klio [65]

Answer:

<em>The distance between the points (1, 7) and (10, 1) is 10.82 units</em>

Step-by-step explanation:

<u>Distance between two points </u>

The distance between points A(x,y) B(w,z) can be calculated with the formula:

$d=\sqrt{(z-y)^2+(w-x)^2}$

We are given the points (1,7) and (10,1), let's use their values and compute the required distance:

$d=\sqrt{(1-7)^2+(10-1)^2}$

$d=\sqrt{(-6)^2+(9)^2}$

$d=\sqrt{36+81}=\sqrt{117}\approx 10.82$

The distance between the points (1, 7) and (10, 1) is 10.82 units

Answer:

6d - 11/2 = 2d - 13/2

6d - 2d = 11/2 -13/2

4d = -2/2

4d = -1

d = -1/4

If "-3<" x/5 < "-1" what is the value of x

Natalka [10]

Answer:

-15 < x < -5

Step-by-step explanation:

-3 < x/5 < -1

Multiply all sides by 5

-3*5 < x/5 *5 < -1*5

-15 < x < -5
