Which dimensions cannot create a triangle? a three sides measuring 6 cm, 8 cm, and 10 cm b three angles measuring 40 degrees, 70

NISA [10]

Answer:

A,C,D are triangles, B is not.

Step-by-step explanation:

Let 3 sides of a triangle be a,b,c.

A triangle have the sum of 3 angles = 180 degree

and

a-b<c<a+b (similar for a and b)

a.<u> </u><u>three sides measuring 6 cm, 8 cm, and 10 </u><u>cm</u><u> </u>

Satisfied the a-b<c<a+b property -> triangle

b. <u>three angles measuring 40 degrees, 70 degrees, and 65 </u><u>degrees</u>

<u> </u>Total of 3 angles = 40+70+65 = 175 > 180

-> not triangle

c. <u>three angles measuring 10 degrees, 25 degrees, and 145 degrees</u>

Total of 3 angles = 10+25+145 = 180

-> triangle

d. <u>three sides measuring 9 m, 15 m, and 9 m</u>

Satisfied the a-b<c<a+b property -> triangle

Answer:

32 ft

Step-by-step explanation:

The perimeter is basically the area of the outside of a shape. To calculate this, you would add up all the sides together and get the answer.

8 + 8 + 8 + 8=32 or you can just do 8*4 which is also 32

So, the answer is 32

HURRY WILL MAKE BRAINLEST!! circle F is shown below. EB is a diameter and the radius is 3 units. Choose the correct

Yuki888 [10]

Answer:

Arc length is equal to $\theta r$ where $\theta$ is the angle in radians and $r$ is the radius.

Question 1:

$\frac{\pi}{2}=\frac{\pi}{6}\times3$

So the angle is CFD.

Question 2:

$\pi=\frac{\pi}{3}\times3$

So the angle is AFE.

Question 3:

$2\pi=\frac{2\pi}{3}\times3$

So the angle is AFB.

Question 4:

$\frac{3\pi}{4}=\frac{\pi}{4}\times3$

So the angle is BFC.

How much 75 octane gas and 90 octane gas should be blended to make 15 gallons of 88 octane gas

Lisa [10]

75x + 90(15-x)=88(15)

75x+1350-90x = 1320

-15x + 1350 = 1320

-15x= -30

x=2

the amount of 75 octane is 2 gallons
the amount of 90 octane is 13 gallons

Hope this helps.
