Is 7.8 cm, 1.1 cm, 9.1 cm a triangle

Mathematics

Anna35 [415]3 years ago

Answer: The sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Since, 11 + 21 > 16, 11 + 16 > 21, and 16 + 21 > 11, you can form a triangle with side lengths 11 mm, 21 mm, and 16 mm.

Step-by-step explanation:

I CAN HELP A GIRL OUT!

anyways...

calculate the difference first.

(-13/12) - 14/9

then, rewrite the expression.

-13/12 - 14/9

the solution is -95/36.

when it's converted to decimal form, it turns into -2.638. so, our BEST estimate for the value of the expression is -2(1/2)       (the second option)

The height of a triangle is 12 centimeters more than its base. The area of the triangle is 189 square centimeters Find the base
telo118 [61]

Answer:

C

Step-by-step explanation:

the area of a triangle is

baseline × height / 2

so, we know in our case

b(b+12) = 189 cm²

b² + 12b - 189 = 0

let's try to solve this by completing the square.

that means we try to find the expression

(b + k)² + c

that is equal to

b² + 12b - 189

(b + k)² + c = b² + 2kb + k² + c = b² + 12b - 189

so,

2k = 12

k = 6

and then

k² + c = -189

6² + c = -189

36 + c = -189

c = -225

(b + 6)² - 225 = 0

(b + 6)² = 225

b + 6 = 15

b = 9

so, the baseline b = 9 cm.

the height b+12 = 9+12 = 21 cm.
