The sides of a triangle have lengths of x, x + 4, and 20. If the longest side is 20, which of the following values of x would ma
GuDViN [60]

Answer:

12<x<16

Step-by-step explanation:

if c^2 > a^2 + b^2

then the triangle is obtuse

since 20 is the longest side

20^2 > x^2 + (x+4)^2

simplify

400 > x^2 +  (x+4)(x+4)

FOIL

400 > (x^2 ) + (x^2 + 4x+4x+16)

combine like terms

400 > (2x^2 + 8x+16)

divide by 2

400/2 > 2x^2  /2 + 8x/2 + 16/2

200 > x^2 + 4x +8

subtract 200 from each side

0> x^2 + 4x +8-200

0> x^2 +4x-192

Factor

0 > (x-12) ( x+16)

using the zero product property

0> x-12    0 > x+16

12>x     -16>x

x must be greater than 12

we know the longest side is 20

x+4 < 20

subtract 4

x< 16


x>12  and x < 16


12<x<16

A car is traveling at a speed of 45 kilometers per hour. What is the car's speed in kilometers per minute? How many kilometers w
oee [108]

Answer:

24 kilometers

Step-by-step explanation:

1.2 kilometers per minute; 12 kilometers

Step-by-step explanation:

We know that 60 minutes makes 1 hour.

Therefore, to convert the speed to kilometers per minute, we simply divide 72 kilometers per hour by 60 minutes:

72 / 60 = 1.2 kilometers per minute.

Distance is given as speed multiplied by time.

Therefore, in 10 mins, the car travels:

1.2 * 20 = 24 kilometers.

The smallest side of a 30-60-90
Aleonysh [2.5K]

Answer: A 30-60-90 triangle is a special right triangle (a right triangle being any triangle that contains a 90 degree angle) that always has degree angles of 30 degrees, 60 degrees, and 90 degrees. Because it is a special triangle, it also has side length values which are always in a consistent relationship with one another.

The basic 30-60-90 triangle ratio is:

Side opposite the 30° angle: x

Side opposite the 60° angle: x*√3

Side opposite the 90° angle: 2x
