If a, b and c are the lengths of the sides of a triangle then

if a ≤ b ≤ c, then a + b > c.

A) 10, 14, 26

10 + 14 = 24 < 26 INCORRECT :(

B) 10, 14, 16

10 + 14 = 24 > 16 CORRECT :)

C) 10, 10, 14

10 + 10 = 20 > 14 CORRECT :)

D) 8, 10, 14

8 + 10 = 18 > 14 CORRECT :)

E) 5, 10, 14

5 + 10 = 15 > 14 CORRECT :)

F) 2, 10, 14

2 + 10 = 12 < 14 INCORRECT :(

<h3>Answer: B) 16, C) 10, D) 8, E) 5</h3>

Find the measure of arc DF (with an explanation of how to solve please!)

allochka39001 [22]

Answer:

mDF = 90°

(Assuming arc mCE is 5x + 10)

Step-by-step explanation:

When we have two chords crossing in a circle, there is a property where the angle in the cross point is equal half the sum of the corresponding arcs.

So in this case, we have:

70° = (mCE + mDF)/2

Assuming mCE is 5x + 10, we have:

70 = (5x + 10 + 11x + 2)/2

70 = (16x + 12)/2

70 = 8x + 6

8x = 64

x = 8

So the arc mDF is:

mDF = 11x + 2 = 11 * 8 + 2 = 90°

Given the points R (6,-2) and T (-9,- 7), find the coordinates of point S on line RT such that the ratio of RS to ST is 3 : 2 p

Sholpan [36]

Answer:

(-3, -5)

Step-by-step explanation:

By using the distance formula, we see that the length of RT is $\sqrt{(6+9)^2+(-2+7)^2}$ which equals $5\sqrt{10}$ .

The ratio of RS to ST is 3:2, so we can write the distance of RS as $(5\sqrt{10} / 5) * 3$ which equals $3\sqrt{10}$ . The distance of ST is then $2\sqrt{10}$ .

Since we know the distance of RS and ST, we can find the coordinates of point S by using the distance formula again:

$\sqrt{(6-x)^2+(-2-y)^2} = 3\sqrt{10}$ and $\sqrt{(-9-x)^2+(-7-y)^2} = 2\sqrt{10}$

We solve for x and y, getting (-3, -5).
