A triangular section of land is fenced off due to contamination. Two sides of the triangle are each 16 meters ( 16m) longer than

the third side.
If 122m of fencing is used to enclose the area, what is the length of the shortest side, in meters?

Answer: the shortest side is 30m

Step-by-step explanation:

Let the shortest side be a meters

If side 2 is 16m longer than the shortest side, then it is (16+a)meters.

The same goes with side 3.

Then,

a + (16+a) + (16+a) = 122m

32 + 3a = 122m

Collecting like terms together,

3a = 122 - 32

3a = 90

Divide by coefficient of a

3a/3 = 90/3

a = 30 meters

Check:

30 + (16+30) + (16+30)

30 + 46 + 46 = 112

Answer:

Shortest side = 30 m long.

Step-by-step explanation:

Let the shortest side be x meters long.

The other 2 sides are both  x + 16 m.

The perimeter is 122 m so

x + 2(x + 16) = 122

x + 2x + 32 = 122

3x = 122 - 32

3x =  90

x = 30 m.

Y-intercept of a line that has a slope of 2 and passes<br> through the point (4, 6).
tia_tia [17]

Answer:

<h2>         b = -2</h2>

Step-by-step explanation:

The point-slope form of equation is: y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope.

m = 2

(4, 6)    ⇒   x₀ = 4,  y₀ = 6

So, the point-slope form of equation:

y - 6 = 2(x - 4)

Changing to the slope-intercept form of the equation of the line (y = mx + b, where m is the slope and b is the y-intercept of the line):

y - 6 = 2x - 8               {add 6 to both sides}

y = 2x - 2    ⇒  b = -2

I really need help with these 2 geometry questions tysm
qwelly [4]

Answer:

180 + 9 - 4 = 185

5x = 185

185/5= 37

A = 37 X 2 - 9 = 65

B = 37 X 2 + 4 = 78

C = 37

A + B + C = 180

65 + 78 + 37 = 180

A = 65 degrees

B = 78 degrees
