Two sides of an obtuse triangle measure 9 inches and 14 inches. The length of longest side is unknown. What is the smallest poss

julia-pushkina [17]

Answer:

17 inches

Step-by-step explanation:

An obtuse triangle is the triangle in which one of the side is the longest. It contains an obtuse angle and the longest side is the side that is opposite to the vertex of the obtuse angle.

Let the three sides of the obtuse triangle be a, b and c respectively with c as the longest side. Let a = 9 inches and b = 14 inches.

Now we know that for an obtuse triangle,

$c^2 > a^2 +b^2$

$c^2 > (9)^2 +(14)^2$

$c^2 > 81 +196$

$c^2 > 277$

c > 16.64

Therefore the smallest possible whole number is 17 inches.

HELP ME PLEASE PLEASE

Ymorist [56]

Answer:

The value of x is 7 and y is 14.

Step-by-step explanation:

The steps are :

$- 3x + y = - 7 - - - (1)$

$y = x + 7 - - - (2)$

$(2)→(1)$

$- 3x + (x + 7) = - 7 \\ - 3x + x + 7 = - 7 \\ - 2x = - 14 \\ x = 7$

$substitute \: x = 7 \: \: into \: \: (2)$

$y = 7 + 7 \\ y = 14$

Solve for x 7 x + 15 equals 38

Galina-37 [17]

Answer:

x = 23/7

Step-by-step explanation:

7 x + 15 equals 38

7x+15 = 38

Subtract 15 from each side

7x+15-15 = 38-15

7x = 23

Divide each side by 7

7x/7 = 23/7

x = 23/7
