Can the side lengths of 12, 15, and 13 form a triangle? Yes No

2 answers:

8 0

My answer is yes! The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side. So the sum of 2 sides, must be greater than the third... I hope this helps please rate and thanks

Yes. 12 and 13 would be the legs, and 15 would be the hypotenuse. This would form a right triangle.

Solve this expression 8÷2*5+(6-4)

Annette [7]

Value of expression $\frac{8}{2}(5) + (6-4)$ is 22 .

<u>Step-by-step explanation:</u>

Here we have the following expression to solve :

8÷2*5+(6-4)

⇒ $(8/2)*5 + (6-4)$

⇒ $\frac{8}{2}(5) + (6-4)$

But 8 = 4(2) , So

⇒ $\frac{4(2)}{2}(5) + (6-4)$

⇒ $4(5) + (6-4)$

⇒ $20 + (6-4)$

⇒ $20 + 2$

⇒ $22$

Therefore, Value of expression $\frac{8}{2}(5) + (6-4)$ is 22 .

A train has 6 identical passenger cars that are each 18 m long.

Gnesinka [82]

Answer:

59m

Step-by-step explanation:

No of passenger cars in the train = 6

length of each passenger cars = 18m

total length of 6 passenger cars = 18 * 6 = 108 m

length of caboose = 10m

total length of train when caboose is included = 108 m + 10 m = 118m

_____________________________________________

Let the length of truck be X m

given that length of train is twice of length of truck = 2*X

but length of train as found above is 118 m

this implies

2X = 118

X = 118/2 = 59m

Therefore length of truck is 59m

Mr. and Mrs. Parker's bed is 2 1/3 yards wide. That also have 2 nightstands that are 22 inches wide. The bedroom wall is 12 1/2

vampirchik [111]

Conversions: to smallest (inches)
n= 22 inches
b= 2 1/3 yard = 84 inches
t= 12 1/2 feet = 150 inches

total space = t
night stand = n (2n for two nightstands)
bed=b

b+2n has to be < or = to t

84+2(22)=x
84+44=128
128 is < 150

therefore the answer is yes they will fit with 22 inches left over.

Find the measure of angle 3<br> I WILL GIVE BRAINLIEST TO THE CORRECT ANSWER

Mice21 [21]

Answer:

82°

Step-by-step explanation:

i. 8x +26 = angle 5 (corresponding angles)

ii. angle 5 = -9x + 179 ( vertically opposite angles)

so,

8x+26= -9x +179 (from i and ii)

or, 17x= 153

therefore, x= 9

now,

angle3 + 8x +26= 180° (linear pair)

angle 3 = 180°- 72-26

hence, angle 3= 82°
