Answer:

74 degrees

Step-by-step explanation:

hey there,

so we know that the angles in a triangle always add up to 180 degrees

because this is an isoceles triange the 2 base angles will always be the same number of degrees.

this means that our situation can be modeled with a simple expression:

2x+32=180

which simplifies to

2x=148

x=74

Formula: A = pq/2

p = d1

q = d2

Substitute with the given values and solve.

A = 12*14/2

A = 168/2

A = 84

Therefore, the ansewr is 84in²

Best of Luck!

DochEvi [55]
1 yard = 3 feet
2/3 of a yard would be 2 feet

4.5 yards = 13.5 feet
13.5-2 = 11.5 feet

11.5 feet = 3.83 yards

therefore at least 11.5 feet or 3.83 yards must be purchased

If y varies inversely with x and y =5 when x=20 find x when y = -4​
sweet-ann [11.9K]

Answer:

x=-25

Step-by-step explanation:

Inverse variation

xy =k

We know x and y

20*5 =k

100 =k

So the formula is

x y = 100

We know y = -4

x (-4) = 100

Divide each side by -4

-4x/-4 = 100/-4

x = -25

Step-by-step explanation:

lets take a look....

In order to find the perimeter of a triangle you have to get the sum of all sides. In other words,

Blue triangle:

p = (4x +2) + (7x + 7) + (5x  - 4) \\ p = 4x + 2 + 7x + 7 + 5x - 4 \\ p = 16x + 5

Red triangle:

p = (x + 3) + (2x - 5) + (x + 7) \\ p = x + 3 + 2x - 5 + x + 7 \\ p = 4x + 5

Difference:

d = (16x + 5) - (4x + 5) \\ d = 16x + 5 - 4x - 5 = 12x \\ d = 12x
