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

Can someone help me identify c(6)=
Vanyuwa [196]

Answer and Step-by-step explanation:

To solve, simply plug 6 in for m in the equation.

C(6) = 50(6) + 79.50

6 times 50 is 300.

300 + 79.50 = 379.50 = C(6)

The answer is 379.5

(Looking at the question again, I don't think what I said is what it is asking for, soo)

The slope of the function given represents the amount that needs to be paid every month. The y-intercept (79.50) represents the initial cost (starting amount) for paying the membership.

Why is ti that when you add two numbers together (5+5,6+6,3+3, etc.) you get an even sum?? I need this for my 8 year-old-brother
astra-53 [7]

Essentially, the rule goes as so: odd + odd = even, even + even = even.

Although that may not be the answer you're looking for, it is a math rule that is never debunked and essentially the premises for why you get an even sum practically always depending on the numbers.

Hope this helps!
